[0036] Figure 15 This is a schematic diagram illustrating an electronic device according to an embodiment of the present disclosure. Detailed Implementation

[0037] In the following description, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components will be omitted.

[0038] In the accompanying drawings and text of this disclosure, the singular form of reference numerals indicating elements may also be used to refer to multiple elements.

[0039] It will be understood that when an element is referred to as being associated with another element (such as "on" another element), the element can be directly on the other element, or an intermediary element can exist between the element and the other element. Conversely, when an element is referred to as being associated with another element (such as "directly on" another element), no intermediary element exists.

[0040] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or segments, these elements, components, areas, layers, and / or segments should not be limited by these terms. These terms are used only to distinguish one element, component, area, layer, or segment from another element, component, area, layer, or segment. Therefore, without departing from the teachings herein, “first element,” “first component,” “first area,” “first layer,” or “first segment” discussed below may be referred to as “second element,” “second component,” “second area,” “second layer,” or “second segment.”

[0041] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, “a,” “an,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both the singular and the plural. Thus, in the claims, a reference to “the” element following a reference to “a” element includes one element and multiple elements. For example, unless the context clearly indicates otherwise, “element” has the same meaning as “at least one element.” “At least one” should not be construed as limited to “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will also be understood that when the terms “comprising” and / or “including” are used in this specification, it indicates the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0042] Furthermore, relative terms such as “below” or “bottom” and “above” or “top” may be used herein to describe the relationship between one element and another as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the relative terms are intended to cover different orientations of the device. For example, if the device in one of the drawings is flipped over, an element described as being “below” the other element will subsequently be positioned “above” the other element. Thus, depending on the specific orientation of the drawing, the term “below” can cover both “below” and “above” orientations. Similarly, if the device in one of the drawings is flipped over, an element described as being “below” or “under” the other element will subsequently be positioned “above” the other element. Thus, the terms “below” or “under” can cover both “above” and “below” orientations.

[0043] Given the measurements discussed and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system), the terms “approximately” or “about” as used herein include stated values ​​and mean within an acceptable range of deviation from a particular value as determined by one of ordinary skill in the art. For example, “approximately” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0044] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms (such as those defined in common dictionaries) shall be interpreted as having a meaning consistent with their context in the relevant field and their meaning in this disclosure, and shall not be interpreted in an idealized or overly formalized sense unless expressly defined herein.

[0045] The embodiments are described herein with reference to cross-sectional views of schematic diagrams as idealized embodiments. Thus, variations in the shape of the illustrated areas due to, for example, manufacturing techniques and / or tolerances will be expected. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the areas shown herein, but should include deviations in shape due to, for example, manufacturing processes. For example, areas shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, acute angles shown may be rounded. Therefore, the areas shown in the drawings are schematic in nature and their shapes are not intended to show the precise shapes of the areas, nor are they intended to limit the scope of the present claims.

[0046] Figure 1 This is a perspective view showing a display device 10 according to an embodiment of the present disclosure.

[0047] Reference Figure 1 The display device 10 may include a display area DA and a non-display area NDA.

[0048] The display area DA can be an area for displaying an image (e.g., a planar area). A plurality of pixels PX can be arranged in the display area DA. The pixels PX can be arranged in a matrix along a first direction DR1 and a second direction DR2 intersecting the first direction DR1. Each of the plurality of pixels PX can emit light. When each of the plurality of pixels PX emits light, the display area DA can display an image. For example, in the display area DA, an image can be displayed on a third direction DR3 intersecting each of the first direction DR1 and the second direction DR2. Lines connected to the pixels PX can be further arranged in the display area DA. For example, lines that are wires and / or signal lines can include data signal lines, gate signal lines, or power lines, etc.

[0049] The non-display area NDA can be a region where no image is displayed (e.g., a planar region). The non-display area NDA is adjacent to the display area DA and can be arranged around the display area DA. For example, the non-display area NDA can surround the display area DA in a planar diagram. The planar diagram can be along a plane (such as a plane formed by...) Figure 1The planes defined by the first direction DR1 and the second direction DR2 intersect or are perpendicular to each other. The thickness of various components or layers of the display device 10 may be defined along a third direction DR3 (e.g., the thickness direction).

[0050] The driver used to drive the pixel PX can be arranged in the non-display area NDA. For example, the driver may include a data driver, a gate driver, a power voltage generator, or a timing controller. The pixel PX can emit light based on the signal received from the driver.

[0051] Display device 10 can detect external input applied from the outside (e.g., outside of display device 10). External input can include various types of input provided from outside display device 10. External input can include not only contact (e.g., physical contact) from an input tool, but also external input applied at a selectable distance from or adjacent to display device 10. Furthermore, external input can take various forms, such as force, pressure, temperature, or light. Input tools can include body parts (such as a part of a user's body), pens, or styluses.

[0052] Display device 10 can sense biometric information from an external object (e.g., a user) applied from the outside. A biometric sensing area for sensing the user's biometric information can be provided within the display area DA of display device 10. For example, the biometric sensing area can be provided in the entire area (e.g., a planar area) of display area DA or a portion of display area DA, or provided to correspond to the entire area (e.g., a planar area) or a portion of display area DA.

[0053] Figure 2 It is shown Figure 1 A cross-sectional view of the display area DA of the display device 10.

[0054] Reference Figure 1 and Figure 2 The display area DA of the display device 10 may include a first light-emitting area LA1, a second light-emitting area LA2, a third light-emitting area LA3, and a non-light-emitting area NLA. Each of the first light-emitting areas LA1, LA2, and LA3 may be a light-emitting area (e.g., a planar area). When light is emitted at each of the first light-emitting areas LA1, LA2, and LA3, the display area DA can display an image. The first light-emitting area LA1, LA2, and LA3 may each correspond to a pixel PX. That is, the planar area of ​​the light-emitting element may define the planar area of ​​the corresponding pixel PX.

[0055] In one embodiment, the first emitting region LA1, the second emitting region LA2, and the third emitting region LA3 can emit light of different wavelength bands. The first emitting region LA1 can emit a first light L1, the second emitting region LA2 can emit a second light L2, and the third emitting region LA3 can emit a third light L3. For example, the first light L1 can be light of the red wavelength band, the second light L2 can be light of the green wavelength band, and the third light L3 can be light of the blue wavelength band, but this disclosure is not limited thereto. In another embodiment, the first emitting region LA1, the second emitting region LA2, and the third emitting region LA3 can emit light of the same wavelength band, or at least one of the first emitting region LA1, the second emitting region LA2, and the third emitting region LA3 can emit light of different wavelength bands.

[0056] although Figure 2 The first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 are shown arranged along the first direction DR1, but this disclosure is not limited thereto, and the arrangement structure of the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can be modified in various ways.

[0057] The non-emitting region NLA can be a region that does not emit light from the display region DA. The non-emitting region NLA can separate the planar regions of the first emitting region LA1, the second emitting region LA2, and the third emitting region LA3. The non-emitting region NLA can be arranged between adjacent first emitting regions LA1, second emitting region LA2, and third emitting region LA3. The non-emitting region NLA can surround each of the first emitting region LA1, second emitting region LA2, and third emitting region LA3 in a planar view, extending around all sides of the emitting region.

[0058] The display device 10 may include a display panel layer DP, an input sensing layer ISL, a color filter layer CFL, and a window WM. The display panel layer DP may include a substrate SUB, a circuit layer DP_CL, a component layer DP_LE, and a package layer TFE.

[0059] The substrate SUB can be made of transparent or opaque materials. Examples of materials that can be used as a substrate SUB include polyimide, quartz, or glass. These can be used alone or in combination with each other.

[0060] The circuit layer DP_CL can be placed on the substrate SUB. The circuit layer DP_CL can include transistors, capacitors, insulating layers, or signal lines, etc.

[0061] The component layer DP_LE can be disposed on the circuit layer DP_CL. The component layer DP_LE may include multiple light-emitting elements (such as a first light-emitting element LE1, a second light-emitting element LE2, and a third light-emitting element LE3) and a pixel defining layer PDL. The first light-emitting element LE1 may include a pixel electrode PE as a first pixel electrode, a first light-emitting layer EL1, and a common electrode CE; the second light-emitting element LE2 may include a pixel electrode PE as a second pixel electrode, a second light-emitting layer EL2, and a common electrode CE; and the third light-emitting element LE3 may include a pixel electrode PE as a third pixel electrode, a third light-emitting layer EL3, and a common electrode CE.

[0062] The pixel electrode PE can be disposed on the circuit layer DP_CL. The pixel electrode PE of the element layer DP-LE can be connected to the circuit layer DP_CL, such as to a transistor connected to the circuit layer DP_CL. For example, the pixel electrode PE can be connected to the transistor through a contact hole penetrating the insulating layer of the circuit layer DP_CL. The pixel electrode PE can include metals, alloys, conductive metal oxides, conductive metal nitrides, or transparent conductive materials, etc. These can be used individually or in combination with each other.

[0063] A pixel defining layer (PDL) can be disposed on a circuit layer (DP_CL) within a non-emitting region (NLA). The PDL may include pixel openings defined therein, the pixel openings exposing at least a portion of the upper surface of a pixel electrode (PE) disposed within the pixel openings. For example, the PDL may cover a side surface of the pixel electrode (PE) and a portion of the upper surface of the pixel electrode (PE) adjacent to the side surface. A first emitting region (LA1), a second emitting region (LA2), and a third emitting region (LA3) may be defined to correspond to the pixel electrode (PE) exposed by the PDL, and the non-emitting region (NLA) may be defined between the first emitting region (LA1), the second emitting region (LA2), and the third emitting region (LA3).

[0064] The pixel defining layer (PDL) may include organic materials such as polyimide resins, epoxy resins, or siloxane resins, or inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride. These may be used alone or in combination with each other. In embodiments, the pixel defining layer (PDL) may include a light-blocking material. For example, the pixel defining layer (PDL) may achieve a black pixel defining layer. The light-blocking material may include carbon black, black dyes, black pigments, metals (e.g., nickel, aluminum, molybdenum, and alloys thereof), metal oxides (e.g., chromium oxide), or metal nitrides (e.g., chromium nitride).

[0065] The first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can be disposed on the pixel electrode PE, respectively. The first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can be disposed in the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3, respectively. The first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can be disposed on the pixel electrode PE exposed by the pixel defining layer PDL, respectively.

[0066] In one embodiment, the first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can emit light of different wavelength bands. For example, the first light-emitting layer EL1 can emit a first light L1, the second light-emitting layer EL2 can emit a second light L2, and the third light-emitting layer EL3 can emit a third light L3. In another embodiment, the first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can emit light of the same wavelength band, or at least one of the first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 can emit light of different wavelength bands.

[0067] For example, each of the first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3 may include a light-emitting layer containing a material that emits light and an auxiliary layer (not shown) on the light-emitting layer. The auxiliary layer may include at least one of a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer.

[0068] The common electrode CE can be disposed on the pixel defining layer PDL and the first light-emitting layer EL1, the second light-emitting layer EL2, and the third light-emitting layer EL3. For example, the common electrode CE can extend continuously in the first light-emitting region LA1, the second light-emitting region LA2, the third light-emitting region LA3, and the non-light-emitting region NLA. The common electrode CE can include metals, alloys, conductive metal oxides, conductive metal nitrides, or transparent conductive materials, etc. These can be used individually or in combination with each other.

[0069] Therefore, the first light-emitting element LE1, which includes a pixel electrode PE, a first light-emitting layer EL1, and a common electrode CE, can be arranged on the substrate SUB in the first light-emitting region LA1; the second light-emitting element LE2, which includes a pixel electrode PE, a second light-emitting layer EL2, and a common electrode CE, can be arranged on the substrate SUB in the second light-emitting region LA2; and the third light-emitting element LE3, which includes a pixel electrode PE, a third light-emitting layer EL3, and a common electrode CE, can be arranged on the substrate SUB in the third light-emitting region LA3.

[0070] The encapsulation layer TFE can be disposed on the common electrode CE. The encapsulation layer TFE can prevent impurities, moisture, or external air from penetrating into the first light-emitting element LE1, the second light-emitting element LE2, and the third light-emitting element LE3. The encapsulation layer TFE may include at least one inorganic encapsulation layer and at least one organic encapsulation layer.

[0071] The input sensing layer (ISL) can be disposed on the display panel layer (DP). For example, the input sensing layer (ISL) can be disposed directly on the encapsulation layer (TFE). The input sensing layer (ISL) can sense external input applied from the outside. The input sensing layer (ISL) may include a first conductive layer (ICL1), a first input insulating layer (IL1), a second conductive layer (ICL2), and a second input insulating layer (IL2). The first input insulating layer (IL1) of the input sensing layer (ISL) can contact the encapsulation layer (TFE) of the display panel layer (DP).

[0072] The first conductive layer ICL1 can be disposed on the encapsulation layer TFE within the non-light-emitting region NLA. The first conductive layer ICL1 can have a single-layer or multi-layer structure and can include multiple conductive patterns. The first conductive layer ICL1 can include metals, alloys, or transparent conductive materials, etc. These can be used individually or in combination with each other.

[0073] The first input insulating layer IL1 can be disposed on and cover the first conductive layer ICL1. The first input insulating layer IL1 can be disposed within the first light-emitting region LA1, the second light-emitting region LA2, the third light-emitting region LA3, and the non-light-emitting region NLA. The first input insulating layer IL1 can comprise organic materials such as acrylic resin or polyimide resin, or inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride. These can be used individually or in combination with each other.

[0074] The second conductive layer ICL2 can be disposed on the first input insulating layer IL1 in the non-light-emitting region NLA. The second conductive layer ICL2 can have a single-layer structure or a multi-layer structure, and can include multiple conductive patterns. Some of the multiple conductive patterns of the second conductive layer ICL2 can be connected (e.g., electrically connected) to the first conductive layer ICL1. The second conductive layer ICL2 can include metals, alloys, or transparent conductive materials, etc. These can be used individually or in combination with each other.

[0075] The second input insulating layer IL2 can be disposed on the first input insulating layer IL1 and the second conductive layer ICL2, and can cover the first input insulating layer IL1 and the second conductive layer ICL2. The second input insulating layer IL2 can be disposed within the first light-emitting region LA1, the second light-emitting region LA2, the third light-emitting region LA3, and the non-light-emitting region NLA. The second input insulating layer IL2 can comprise organic materials such as acrylic resin or polyimide resin, or inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride. These can be used individually or in combination with each other.

[0076] although Figure 2 The diagram shows an input sensing layer ISL comprising a first conductive layer ICL1 and a second conductive layer ICL2, as well as a first input insulating layer IL1 and a second input insulating layer IL2, but this disclosure is not limited thereto. For example, the input sensing layer ISL may further include a substrate insulating layer (not shown) disposed between the first conductive layer ICL1 and the encapsulation layer TFE, and may include only one of the first conductive layer ICL1 and the second conductive layer ICL2, or may not include the second input insulating layer IL2.

[0077] Color filter layer CFL, serving as a color control (or color conversion) layer, can be disposed on input sensing layer ISL. The color filter layer CFL may include a first barrier layer BK1, a first color filter CF1, a second color filter CF2, a third color filter CF3, a second barrier layer BK2, a first reflection control pattern RCP1, a second reflection control pattern RCP2, and an outer coating OCL. The first and second barrier layers together can define the barrier layers of the display device 10. Color filters CF1, CF2, and CF3 face the encapsulation layer TFE along the thickness direction.

[0078] A first dam BK1, which is the solid portion (e.g., a solid material portion) of the first dam layer, can be arranged on the input sensing layer ISL within a non-light-emitting region NLA. The first dam BK1 can define an area in which a first color filter CF1, a second color filter CF2, and a third color filter CF3 are arranged. The first dam BK1 can define an opening as a first dam opening in which the first color filter CF1, the second color filter CF2, and the third color filter CF3 are arranged respectively, and can surround each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 in a plan view.

[0079] In an embodiment, the first dam BK1 may include a light-blocking material. The light-blocking material may include carbon black, black dye, black pigment, metal, metal oxide, or metal nitride, etc. Additionally, the light-blocking material may be liquid-repellent relative to the materials included in the first color filter CF1, the second color filter CF2, and the third color filter CF3. Because the first dam BK1 includes a light-blocking material, reflection of external light caused by the lower component can be reduced, and color mixing between the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can be prevented.

[0080] The first dam BK1 may have a first thickness TH1 in the thickness direction. The first thickness TH1 may be the distance or height in the third direction DR3 from the first surface of the first dam BK1 closest to the input sensing layer ISL to the second surface of the first dam BK1 furthest from the input sensing layer ISL and opposite to the first surface. In an embodiment, the first thickness TH1 may be the maximum thickness of the first dam layer.

[0081] The first dam BK1 may have a first width W1 in the width direction along the planar direction. The first width W1 may be the minimum length (or dimension) of the first dam BK1 in the first direction DR1. For example, the first width W1 may be the length of the second surface of the first dam BK1 in the first direction DR1. That is, the width of the first dam BK1 may increase in the direction from the second surface to the first surface. In an embodiment, the dam structure (e.g., the first dam layer together with the second dam layer) includes a first dam BK1 having a first width W1 in the width direction along the encapsulation layer TFE and a second dam BK2 having a second width W2 in the width direction that is less than or equal to the first width W1 on the first dam BK1. The width direction may be defined along any of a plurality of planar directions such as the DR1-DR2 plane (i.e., the plane defined by the first direction DR1 and the second direction DR2).

[0082] A first color filter CF1 can be disposed on the input sensing layer ISL within the first light-emitting region LA1. The first color filter CF1 can overlap with the first light-emitting element LE1 in a plan view. For example, the first color filter CF1 can be arranged to correspond to the first light-emitting layer EL1. The first color filter CF1 can transmit the first light L1 and can block light with a wavelength band different from the wavelength band of the first light L1. For example, the first color filter CF1 can transmit light with a red wavelength band and can block light with green and blue wavelength bands, but this disclosure is not limited thereto. Therefore, the first light L1 can be emitted to the outside within the first light-emitting region LA1 (e.g., on the third-direction DR3).

[0083] A second color filter CF2 can be arranged on the input sensing layer ISL within the second light-emitting region LA2. The second color filter CF2 can overlap with the second light-emitting element LE2 in a planar view. For example, the second color filter CF2 can be arranged to correspond to the second light-emitting layer EL2. The second color filter CF2 can transmit the second light L2 and can block light with a wavelength band different from the wavelength band of the second light L2. For example, the second color filter CF2 can transmit light with a green wavelength band and can block light with red and blue wavelength bands, but this disclosure is not limited thereto. Therefore, the second light L2 can be emitted to the outside within the second light-emitting region LA2 (e.g., on a third-direction DR3).

[0084] A third color filter CF3 can be arranged on the input sensing layer ISL within the third light-emitting region LA3. The third color filter CF3 can overlap with the third light-emitting element LE3 in a plan view. For example, the third color filter CF3 can be arranged to correspond to the third light-emitting layer EL3. The third color filter CF3 can transmit the third light L3 and can block light with a wavelength band different from the wavelength band of the third light L3. For example, the third color filter CF3 can transmit light with a blue wavelength band and can block light with red and green wavelength bands, but this disclosure is not limited thereto. Therefore, the third light L3 can be emitted to the outside within the third light-emitting region LA3 (e.g., on the third-direction DR3). In embodiments, within the display device 10, light-emitting elements are provided in plurality, including a first light-emitting element LE1 emitting a first light L1, a second light-emitting element LE2 emitting a second light L2, and a third light-emitting element LE3 emitting a third light L3. The color filters are provided in a plurality of cases, including a first color filter CF1 that overlaps with the first light-emitting element LE1 in the thickness direction, a second color filter CF2 that overlaps with the second light-emitting element LE2 in the thickness direction, and a third color filter CF3 that overlaps with the third light-emitting element LE3 in the thickness direction.

[0085] The first color filter CF1, the second color filter CF2, and the third color filter CF3 may have a second thickness TH2 in the thickness direction. More specifically, the first color filter CF1 and the second color filter CF2 may have a second thickness TH2 in the thickness direction. The second thickness TH2 may be the length on the third-direction DR3 from the surface of the first color filter CF1, the second color filter CF2, and the third color filter CF3 (more specifically, the first color filter CF1 and the second color filter CF2) adjacent to the input sensing layer ISL to the highest point of the first color filter CF1, the second color filter CF2, and the third color filter CF3 (more specifically, the first color filter CF1 and the second color filter CF2) spaced apart from the input sensing layer ISL. For example, each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 may have a dome shape in a cross-sectional view. For example, each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 may be formed by an inkjet process. In other words, a color filter is an inkjet pattern of the color filter material.

[0086] In an embodiment, the second thickness TH2 may be greater than the first thickness TH1. The second thickness TH2 may be the maximum size of the corresponding color filter. For example, the second thickness TH2 may be about 1 micrometer (μm) to about 2 micrometers (μm) greater than the first thickness TH1, but this disclosure is not limited thereto.

[0087] A second dam BK2 of the dam (or dam structure) may be disposed on the first dam BK1 within the non-light-emitting region NLA. The second dam BK2 may define an opening as a second dam opening of the dam layer. The first dam opening may overlap with the second dam opening to define a dam opening of the dam layer. In an embodiment, the second dam BK2 may include a liquid-repellent material. The second dam BK2 may be liquid-repellent relative to the material included in the first reflection control pattern RCP1 and the second reflection control pattern RCP2. The second dam layer may protrude from the first dam layer throughout the entire dam layer of the display device 10.

[0088] The second dam BK2 may include a material different from that of the first dam BK1. For example, the second dam BK2 may include organic materials such as acrylic resin or polyimide resin, or inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride. However, this disclosure is not limited thereto, and the second dam BK2 may include various materials that control reflections from the first dam BK1. For example, the second dam BK2 may include a material having a smaller surface roughness than the first dam BK1, and therefore, reflections on the surface of the first dam BK1 are reduced, thereby reducing reflections caused by external light from the display device 10.

[0089] The second dike BK2 may have a second width W2 in the width direction. The second width W2 may be the maximum length of the second dike BK2 in the first direction DR1. For example, the second width W2 may be the length of the surface of the second dike BK2 closest to the first dike BK1 in the first direction DR1. In an embodiment, the second width W2 may be less than or equal to the first width W1. Steps of the dike layers may be formed at the dike opening by the first and second dike layers. Here, the side surface (or sidewall) of each of the first and second dike layers may define the dike opening.

[0090] Since the second thickness TH2 of the first color filter CF1, the second color filter CF2, and the third color filter CF3 can be greater than the first thickness TH1 of the first dam BK1, and the second width W2 of the second dam BK2 can be less than or equal to the first width W1 of the first dam BK1, grooves can be defined, in plurality of them, at stepped portions of the sidewalls of the dam layer between each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 and the second dam BK2. In an embodiment, a corresponding groove is defined by the surface of a corresponding one of the color filters CF1, CF2, and CF3 and the surface of the second dam BK2.

[0091] The first groove H1 can be defined between the first color filter CF1 and the second embankment BK2, the second groove H2 can be defined between the second color filter CF2 and the second embankment BK2, and the third groove H3 can be defined between the third color filter CF3 and the second embankment BK2. Each groove can be defined at the corresponding embankment opening by the side wall of the second embankment BK2, the upper surface of the first embankment BK1 and the side wall of the second embankment BK2 forming a step, and the upper surface of the corresponding color filter.

[0092] A first reflection control pattern RCP1 can be arranged in a first groove H1, and a second reflection control pattern RCP2 can be arranged in a second groove H2. For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can be formed by an inkjet process. Each reflection control pattern can be a separate pattern of reflective material. That is, the reflection control pattern is an inkjet pattern of reflective or reflective material.

[0093] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of reflected light as external light reflected within and / or from the display device 10. The first reflection control pattern RCP1 may include colored ink that corrects the color of reflected light in the first light-emitting region LA1, and the second reflection control pattern RCP2 may include colored ink that corrects the color of reflected light in the second light-emitting region LA2. For example, the first reflection control pattern RCP1 may include colored ink that corrects the color of the first light L1 (e.g., red), and the second reflection control pattern RCP2 may include colored ink that corrects the color of the second light L2 (e.g., green). For a reflection control pattern that "corrects" the color of reflected light, the color of the reflection control pattern can be the same as the color of the light emitted from the luminous area, or the color of the reflection control pattern can be a color related to the color of the light emitted from the luminous area. The material of the reflection control pattern can be used to absorb or block light of colors other than the colored light emitted from the luminous area, or the material of the reflection control pattern can be used to reflect the colored light emitted from the luminous area while minimizing the reflection of other colors of light, etc., in order to enhance the colored light emitted from the luminous area and minimize the reflection of other colors of light emitted in the luminous area.

[0094] In this embodiment, the light emitted from the light-emitting region has a color, and the color of the corresponding reflection control pattern is the same as the color of the light emitted from the light-emitting region. For example, the color of the first reflection control pattern RCP1 is the same as the color of the first light L1, and the color of the second reflection control pattern RCP2 is the same as the color of the second light L2.

[0095] For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may include ink of primary colors (e.g., red and green). Here, the color of the reflection control pattern may be the same as the color of the light emitted from the emitting region.

[0096] In another example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may include a secondary color ink (e.g., cyan, magenta, or yellow). Here, the reflection control pattern with a secondary color may be a color related to the color of light emitted from the light-emitting area, in order to enhance the reflection of colored light emitted from the light-emitting area while minimizing the reflection of light of colors other than the colored light emitted from the light-emitting area. In embodiments, the respective reflection control patterns have primary colors including red or green, or secondary colors including cyan, magenta, or yellow.

[0097] Since the first reflection control pattern RCP1 is arranged adjacent to the first color filter CF1, and the second reflection control pattern RCP2 is arranged adjacent to the second color filter CF2, when external light is reflected from the display device 10, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can affect the color quality of the reflected light. For example, the color quality of the reflected light can be controlled to provide a comfortable color for the user of the display device 10. In addition, since the first reflection control pattern RCP1 and the second reflection control pattern RCP2 respectively include inks that correct the color quality of the first light L1 and the second light L2, the color reproduction of the display device 10 can be improved.

[0098] The color, size, or area of ​​the first reflection control pattern RCP1 and the second reflection control pattern RCP2 are not limited, and various adjustments can be made according to the color quality required by the display device 10, the shape or planar area of ​​each of the first light-emitting area LA1, the second light-emitting area LA2, and the third light-emitting area LA3, as well as the shape or planar area of ​​the first color filter CF1, the second color filter CF2, and the third color filter CF3.

[0099] In an embodiment, the dam openings can each be closed openings defined along a plane (e.g., the DR1-DR2 plane). Here, the solid material portion of the dam layer surrounds and defines the closed dam openings. Grooves can surround the respective color filters, allowing reflective material to form a reflection control pattern around the respective color filter. In a plan view, the reflection control pattern can have a closed shape around the outer edge of the respective color filter.

[0100] The outer coating OCL can be disposed on the first color filter CF1, the second color filter CF2, and the third color filter CF3, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2. The outer coating OCL can comprise organic materials such as acrylic resin or epoxy resin. The outer coating OCL can have a selective thickness and can planarize the upper surface of the color filter layer CFL.

[0101] The window membrane (WM) can be disposed on the color filter layer (CFL). The window membrane can include optically transparent materials. For example, the window membrane can include glass or plastic. The window membrane can have a single-layer or multi-layer structure. For example, the window membrane can include multiple plastic films bonded together with an adhesive, or it can include a glass substrate and plastic films bonded together with an adhesive. The window membrane can be bonded to the color filter layer (CFL) via an adhesive layer. For example, the adhesive layer can include optically transparent adhesives, optically transparent adhesive resins, or pressure-sensitive adhesives, etc.

[0102] The display device 10 according to embodiments of the present disclosure may include a second barrier BK2 disposed on a first barrier BK1, and a first reflection control pattern RCP1 and a second reflection control pattern RCP2 disposed in a first groove H1 and a second groove H2 respectively defined between a first color filter CF1 and a second color filter CF2 and the second barrier BK2. The second barrier BK2 can reduce reflection from the first barrier BK1, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can correct the color quality of the reflected light. Therefore, the reflection of external light from the display device 10 can be reduced, and the color quality of the reflected light from the display device 10 can be improved.

[0103] Figure 3 , Figure 4 , Figure 5 and Figure 6 This illustrates the manufacture (or provision) of a display device 10 according to an embodiment of the present disclosure (see [link]). Figure 1 (A magnified cross-sectional view of the process in the method.)

[0104] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The described method of manufacturing (or providing) the display device 10 may be a manufacturing reference Figure 1 and Figure 2 The method of the display device 10 is described below. Redundant descriptions will be omitted or simplified in the following text.

[0105] Reference Figure 3 A circuit layer DP_CL, a pixel electrode PE, a pixel defining layer PDL, a first light-emitting layer EL1, a second light-emitting layer EL2 and a third light-emitting layer EL3, a common electrode CE, a package layer TFE, a first conductive layer ICL1, a first input insulating layer IL1, a second conductive layer ICL2 and a second input insulating layer IL2 can be sequentially formed (or provided) on the substrate SUB. Therefore, an input sensing layer ISL can be formed on the display panel layer DP.

[0106] A first dam BK1 can be formed on the input sensing layer ISL in the non-emitting region NLA to define a first dam opening corresponding to the emitting region. The first dam BK1 can be formed to have a first thickness TH1 in the third direction DR3 and a first width W1 in the first direction DR1. The first dam BK1 can include a light-blocking material and can be liquid-repellent relative to materials included in the first color filter CF1, the second color filter CF2, and the third color filter CF3. The first width W1 defines the width of the first dam opening between adjacent portions of the first dam BK1.

[0107] A first color filter CF1 can be formed on the input sensing layer ISL in the first light-emitting region LA1, a second color filter CF2 can be formed on the input sensing layer ISL in the second light-emitting region LA2, and a third color filter CF3 can be formed on the input sensing layer ISL in the third light-emitting region LA3.

[0108] In this embodiment, the first color filter CF1, the second color filter CF2, and the third color filter CF3 can selectively transmit light of different wavelength bands. The first color filter CF1 can selectively transmit a first light (e.g., Figure 2 The first light L1), and the second color filter CF2 can selectively transmit a second light (e.g., Figure 2 The second light L2), and the third color filter CF3 can selectively transmit the third light (e.g., Figure 2 The third light (L3). For example, the first color filter CF1 can transmit light in the red wavelength band, the second color filter CF2 can transmit light in the green wavelength band, and the third color filter CF3 can transmit light in the blue wavelength band.

[0109] The first color filter CF1, the second color filter CF2, and the third color filter CF3 (more specifically, the first color filter CF1 and the second color filter CF2) can be formed to have a second thickness TH2 on the third-direction DR3. In an embodiment, the second thickness TH2 can be greater than the first thickness TH1. For example, each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 can be formed to have a dome shape in a cross-sectional view. In an embodiment, the color filters can be formed in the first dike openings respectively before the second dike layer is provided. The initial color control layer can include the first dike layer and the color filters on the input sensing layer ISL.

[0110] Reference Figure 4 A second dam BK2 can be formed on the first dam BK1 of the initial color control layer in the non-emitting region NLA to define second dam openings that overlap with the openings of the first dam. The second dam BK2 can be formed to have a second width W2 in the first direction DR1. The second width W2 defines the width of the second dam openings between adjacent portions of the second dam BK2. The width of the second dam openings can be greater than the width of the first dam openings to provide a step in the dam layer.

[0111] When the second dam BK2 is formed, grooves can be defined between each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 and the second dam BK2. A first groove H1 can be formed between the first color filter CF1 and the second dam BK2, a second groove H2 can be formed between the second color filter CF2 and the second dam BK2, and a third groove H3 can be formed between the third color filter CF3 and the second dam BK2. Since the color filters at the corresponding dam openings protrude upwards from the first dam BK1, the steps of the dam layer, together with the upwardly protruding upper surface, define grooves at the corresponding dam openings.

[0112] The second barrier BK2 can be formed of a material different from that of the first barrier BK1. The second barrier BK2 can be formed of various materials that control reflection from the first barrier BK1. For example, the second barrier BK2 can include organic materials such as acrylic resin or polyimide resin, or inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride. Additionally, the second barrier BK2 can be formed of a liquid-repellent material. The second barrier BK2 can be relative to the material included in the first reflection control pattern RCP1 (see...). Figure 6 ) and the second reflection control pattern RCP2 (see Figure 6 The material in ) has liquid-repellent properties.

[0113] Reference Figure 5 and Figure 6 A first reflection control pattern RCP1 can be formed in the first groove H1, and a second reflection control pattern RCP2 can be formed in the second groove H2.

[0114] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of the reflected light. For example, the first reflection control pattern RCP1 can be formed in the first groove H1 by dripping and curing colored ink that corrects the color of the reflected light in the first light-emitting area LA1, and the second reflection control pattern RCP2 can be formed in the second groove H2 by dripping and curing colored ink that corrects the color of the reflected light in the second light-emitting area LA2. For example, the first reflection control pattern RCP1 may be formed by colored ink that corrects red, and the second reflection control pattern RCP2 may be formed by colored ink that corrects green. For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may be formed by ink of a primary color or a secondary color.

[0115] In an embodiment, within the corresponding embankment opening (or luminescent area), the reflective material provided at the groove can provide a continuous reflection control pattern extending along the outer edge of the color filter. Such a continuous reflection control pattern can be formed in a planar view into a closed shape having a shape corresponding to the shape of the outer edge of the color filter. At the luminescent area, the reflection control pattern can overlap with the outer edge of the color filter and expose the color filter to the outside of the reflection control pattern.

[0116] The order in which the first reflection control pattern RCP1 and the second reflection control pattern RCP2 are formed is not limited. For example, by forming the first reflection control pattern RCP1, illuminating external light to observe the reflected light, such as in an inspection process, and then forming the second reflection control pattern RCP2 and illuminating external light to observe the reflected light, the color quality of the reflected light can be adjusted. In another example, by forming the second reflection control pattern RCP2, illuminating external light to observe the reflected light, and then forming the first reflection control pattern RCP1 and illuminating external light to observe the reflected light, the color quality of the reflected light can be adjusted.

[0117] Return to reference Figure 2 An outer coating OCL can be formed on the first color filter CF1, the second color filter CF2 and the third color filter CF3, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2 to form a color filter layer CFL.

[0118] A window WM can be formed on the color filter layer CFL, and therefore, it is possible to manufacture Figure 2 The display device 10 shown in the figure.

[0119] Figure 7 This is a cross-sectional view showing a display device 11 according to an embodiment of the present disclosure.

[0120] In addition to the second input insulating layer IL2, refer to Figure 7 The described display device 11 can be used with reference to Figure 1 and Figure 2 The described display device 10 is substantially the same as or similar to the one described above. Redundant descriptions will be omitted or simplified in the following text.

[0121] Reference Figure 7 The display device 11 may include a first light-emitting region LA1, a second light-emitting region LA2, a third light-emitting region LA3, and a non-light-emitting region NLA. Each of the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 may be a region that emits light, and the non-light-emitting region NLA may be a region that does not emit light.

[0122] In this embodiment, the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can emit light of different wavelength bands. The first light-emitting region LA1 can emit a first light L1, the second light-emitting region LA2 can emit a second light L2, and the third light-emitting region LA3 can emit a third light L3. For example, the first light L1 can be light of the red wavelength band, the second light L2 can be light of the green wavelength band, and the third light L3 can be light of the blue wavelength band, but this disclosure is not limited thereto.

[0123] The display device 11 may include a display panel layer DP, an input sensing layer ISL, a color filter layer CFL, and a window WM.

[0124] The display panel layer DP may include a substrate SUB, a circuit layer DP_CL, a component layer DP_LE, and a package layer TFE. The input sensing layer ISL may be disposed on the display panel layer DP and may include a first conductive layer ICL1, a first input insulating layer IL1, a second conductive layer ICL2, and a second input insulating layer IL2.

[0125] The first conductive layer ICL1 can be arranged in the non-light-emitting area NLA on the display panel layer DP, and can include multiple conductive patterns.

[0126] The first input insulating layer IL1 can be arranged on the first conductive layer ICL1 and can cover the first conductive layer ICL1.

[0127] The second conductive layer ICL2 can be disposed on the first input insulating layer IL1 in the non-light-emitting region NLA, and can include multiple conductive patterns. Some of the multiple conductive patterns of the second conductive layer ICL2 can be connected to the first conductive layer ICL1.

[0128] The second input insulating layer IL2 may be disposed on the first input insulating layer IL1 and the second conductive layer ICL2, and may cover at least a portion of each of the first input insulating layer IL1 and the second conductive layer ICL2.

[0129] In an embodiment, the second input insulating layer IL2 may be disposed in the first light-emitting region LA1 and the second light-emitting region LA2, but may not be disposed in the third light-emitting region LA3. For example, the second input insulating layer IL2 may be disposed in the first light-emitting region LA1 and the second light-emitting region LA2 that emits light with relatively long wavelength bands, and may not overlap with the third light-emitting region LA3 that emits light with relatively short wavelength bands. Additionally, the second input insulating layer IL2 may be disposed in at least a portion of the non-light-emitting region NLA. Areas where the second input insulating layer IL2 is not disposed may have recesses formed within the second input insulating layer IL2.

[0130] In this embodiment, the second input insulating layer IL2 may include scattering particles. These scattering particles may be dispersed within the second input insulating layer IL2. For example, the scattering particles may include titanium oxide (TiO2), zinc oxide (ZnO), zirconium oxide (ZrO2), aluminum oxide (Al2O3), chromium oxide (CrO2), or silicon oxide (SiO2), etc. The scattering particles may be spherical, elliptical, or amorphous. The average diameter or content of the scattering particles is not limited and can be adjusted in various ways according to the light extraction efficiency of the display device 11 or the characteristics of the second input insulating layer IL2.

[0131] The scattering particles can scatter light reflected from the lower component and propagating to the outside, thereby preventing color banding caused by reflection from being visually identifiable or reducing the degree to which it is visually identifiable. In addition, since the scattering particles are not arranged in the third light-emitting region LA3 that emits the third light L3, the reduction in the light extraction efficiency of the display device 11 can be minimized.

[0132] although Figure 7 It is shown that the second input insulating layer IL2 is not arranged in the third light-emitting region LA3, but this disclosure is not limited thereto, and in embodiments, the second input insulating layer IL2, which includes scattering particles, may be further arranged in the third light-emitting region LA3.

[0133] The color filter layer CFL can be arranged on the input sensing layer ISL, and can include a first dam BK1, a first color filter CF1, a second color filter CF2, a third color filter CF3, a second dam BK2, a first reflection control pattern RCP1, a second reflection control pattern RCP2, and an outer coating OCL.

[0134] The first dam BK1 can be disposed on the input sensing layer ISL within the non-light-emitting region NLA. For example, when the second input insulating layer IL2 does not cover a portion of the second conductive layer ICL2, the first dam BK1 can cover a portion of the second conductive layer ICL2. Here, the first dam BK1 can extend to contact the first input insulating layer IL1 and provide an opening at the third light-emitting region LA3. The depth of the first dam opening at the third light-emitting region LA3 can be greater than the depth of the first dam opening at the first light-emitting region LA1 or the second light-emitting region LA2. That is, the first dam BK1 can extend into the recess of the second input insulating layer IL2.

[0135] In an embodiment, the first dam BK1 may include a light-blocking material and may be liquid-repellent relative to the materials included in the first color filter CF1, the second color filter CF2, and the third color filter CF3. The first dam BK1 may have a first width W1 in a first direction DR1 and may have a first thickness TH1 in a third direction DR3. The first thickness TH1 may be the length of the first dam BK1 overlapping the second input insulating layer IL2 in a plan view in the third direction DR3. That is, with the upper surface of the second input insulating layer IL2 used as a reference, the first dam BK1 may have at least the first thickness TH1.

[0136] A first color filter CF1 can be disposed on the input sensing layer ISL in the first light-emitting region LA1, a second color filter CF2 can be disposed on the input sensing layer ISL in the second light-emitting region LA2, and a third color filter CF3 can be disposed on the input sensing layer ISL in the third light-emitting region LA3. The third color filter CF3 can extend into a recess in the second input insulating layer IL2. Within the first dam layer, the entire width of the first dam BK1 on one side of the third light-emitting region LA3 can be within the recess in the second input insulating layer IL2, the portion of the width of the first dam BK1 adjacent to the entire width of the first dam BK1 on one side of the third light-emitting region LA3 can be within the recess in the second input insulating layer IL2, and the remaining width portion extends from the recess and extends to the upper surface of the second input insulating layer IL2, and / or the entire width of the first dam BK1 on one side of the third light-emitting region LA3 can be outside the recess in the second input insulating layer IL2 (e.g., Figure 7 The first dike on the left (BK1) in the middle.

[0137] The first color filter CF1 can selectively transmit the first light L1, the second color filter CF2 can selectively transmit the second light L2, and the third color filter CF3 can selectively transmit the third light L3.

[0138] The first color filter CF1, the second color filter CF2, and the third color filter CF3 (more specifically, the first color filter CF1 and the second color filter CF2) may have a second thickness TH2 on the third-direction DR3. Here, the second thickness TH2 may be defined with reference to the upper surface of the second input insulating layer IL2. In an embodiment, the second thickness TH2 may be greater than the first thickness TH1. Since the depth of the dam opening at the third light-emitting region LA3 is increased by omitting the second input insulating layer IL2 at the third light-emitting region LA3, the total thickness of the third color filter CF3 may be greater than the total thickness of the other color filters. However, the third color filter CF3 still defines the third groove H3 together with the step of the dam layer exposed at the dam opening of the third light-emitting region LA3.

[0139] The second dam BK2 can be disposed on top of the first dam BK1 in the non-luminescent region NLA. In an embodiment, the second dam BK2 can be liquid-repellent relative to the materials included in the first reflection control pattern RCP1 and the second reflection control pattern RCP2. The second dam BK2 can include various materials that control reflection from the first dam BK1. The second dam BK2 can have a second width W2 in the first direction DR1. In an embodiment, the second width W2 can be less than or equal to the first width W1.

[0140] Since the second thickness TH2 can be greater than the first thickness TH1, and the second width W2 can be less than or equal to the first width W1, the first groove H1 can be defined between the first color filter CF1 and the second dam BK2, the second groove H2 can be defined between the second color filter CF2 and the second dam BK2, and the third groove H3 can be defined between the third color filter CF3 and the second dam BK2.

[0141] The first reflection control pattern RCP1 can be arranged in the first groove H1, and the second reflection control pattern RCP2 can be arranged in the second groove H2.

[0142] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of the reflected light when external light is reflected from the display device 11. The first reflection control pattern RCP1 may include colored ink that corrects the color of the reflected light in the first light-emitting area LA1, and the second reflection control pattern RCP2 may include colored ink that corrects the color of the reflected light in the second light-emitting area LA2. For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may include primary or secondary color ink.

[0143] When external light is reflected from the display device 11, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can affect the color quality of the reflected light. In addition, the color reproduction of the display device 11 can be improved by the first reflection control pattern RCP1 and the second reflection control pattern RCP2.

[0144] The outer coating OCL can be arranged on the first color filter CF1, the second color filter CF2 and the third color filter CF3, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2, and the window WM can be arranged on the color filter layer CFL.

[0145] Figure 8 This is a cross-sectional view showing a display device 20 according to an embodiment of the present disclosure.

[0146] In addition to the color filter layer CFL, refer to Figure 8The described display device 20 can be used with reference to Figure 1 and Figure 2 The described display device 10 is substantially the same as or similar to the one described above. Redundant descriptions will be omitted or simplified in the following text.

[0147] Reference Figure 8 The display device 20 may include a first light-emitting region LA1, a second light-emitting region LA2, a third light-emitting region LA3, and a non-light-emitting region NLA. Each of the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 may be a region that emits light, and the non-light-emitting region NLA may be a region that does not emit light.

[0148] In this embodiment, the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can emit light of different wavelength bands. The first light-emitting region LA1 can emit a first light L1, the second light-emitting region LA2 can emit a second light L2, and the third light-emitting region LA3 can emit a third light L3. For example, the first light L1 can be light of the red wavelength band, the second light L2 can be light of the green wavelength band, and the third light L3 can be light of the blue wavelength band, but this disclosure is not limited thereto.

[0149] The display device 20 may include a display panel layer DP, an input sensing layer ISL, a color filter layer CFL, and a window WM. The display panel layer DP may include a substrate SUB, a circuit layer DP_CL, a component layer DP_LE, and a package layer TFE.

[0150] The input sensing layer ISL can be disposed on the display panel layer DP. The input sensing layer ISL may include a first conductive layer ICL1, a first input insulating layer IL1, a second conductive layer ICL2, and a second input insulating layer IL2.

[0151] The color filter layer CFL can be disposed on the input sensing layer ISL. The color filter layer CFL may include a first dam BK1, a first color filter CF1, a second color filter CF2, a second dam BK2, a first reflection control pattern RCP1, a second reflection control pattern RCP2, and an outer coating OCL.

[0152] The first dam BK1 can be arranged on the input sensing layer ISL within the third light-emitting region LA3 and the non-light-emitting region NLA. The first dam BK1 can define an area in which the first color filter CF1 and the second color filter CF2 are arranged. The first dam BK1 can define an opening in which the first color filter CF1 and the second color filter CF2 are arranged respectively, and can surround each of the first color filter CF1 and the second color filter CF2 in a plan view.

[0153] In the region adjacent to the first luminous region LA1 and the second luminous region LA2, the first embankment BK1 may have a first width W1 in the first direction DR1 and a first thickness TH1 in the third direction DR3. The first width W1 may be the length of the first embankment BK1 in the first direction DR1 in the non-luminous region NLA between the first luminous region LA1 and the second luminous region LA2.

[0154] The first embankment BK1, adjacent to the third luminescent region LA3, can extend continuously from the non-luminescent region NLA and into the third luminescent region LA3 to overlap with it. The extended portion of the first embankment BK1 can overlap with the entire third luminescent region LA3.

[0155] In an embodiment, the extension of the first dam BK1 can transmit the third light L3 and block light of a wavelength band different from that of the third light L3. The first dam BK1 can selectively transmit light of relatively short wavelength bands. For example, the first dam BK1 can transmit light of the blue wavelength band and block light of the red and green wavelength bands, but this disclosure is not limited thereto. Therefore, the third light L3 can be emitted to the outside in the third light-emitting region LA3 (e.g., on the third-direction DR3). Here, the extension of the first dam BK1 can have a third color filter function, while the third color filter CF3, as described with respect to other embodiments, is excluded from the third light-emitting region LA3.

[0156] A first color filter CF1 can be disposed on the input sensing layer ISL in the first light-emitting region LA1. The first color filter CF1 can transmit the first light L1 and can block light with a wavelength band different from the wavelength band of the first light L1. For example, the first color filter CF1 can transmit light with a red wavelength band and can block light with green and blue wavelength bands, but this disclosure is not limited thereto.

[0157] A second color filter CF2 can be disposed on the input sensing layer ISL within the second light-emitting region LA2. The second color filter CF2 can transmit the second light L2 and can block light with a wavelength band different from that of the second light L2. For example, the second color filter CF2 can transmit light with a green wavelength band and can block light with red and blue wavelength bands, but this disclosure is not limited thereto.

[0158] The first color filter CF1 and the second color filter CF2 may have a second thickness TH2 in the third direction DR3. For example, each of the first color filter CF1 and the second color filter CF2 may have a dome shape in the cross-sectional view. In an embodiment, the second thickness TH2 may be greater than the first thickness TH1.

[0159] The second barrier BK2 can be disposed on top of the first barrier BK1 in the non-emitting region NLA. The second barrier BK2 can transmit the first light L1 and can block light of a wavelength band different from the wavelength band of the first light L1. For example, the second barrier BK2 can be made of the same material as the first color filter CF1. For example, the second barrier BK2 can transmit light of the red wavelength band and can block light of the green and blue wavelength bands, but this disclosure is not limited thereto.

[0160] Since the first dam BK1, which selectively transmits the third light L3, and the second dam BK2, which selectively transmits the first light L1, are stacked in the non-light-emitting region NLA, the reflection of external light caused by the lower component reflecting the light can be reduced, and color mixing between the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can be prevented. Furthermore, reflection from the surface of the first dam BK1 can be reduced, thereby reducing reflection caused by external light from the display device 20.

[0161] although Figure 8 The diagram shows a first dam BK1 that transmits the third light L3 and a second dam BK2 that transmits the first light L1 stacked in a non-emitting region NLA, but this disclosure is not limited thereto. For example, various modified structures can be applied to prevent color mixing between the first emitting region LA1, the second emitting region LA2, and the third emitting region LA3, and to reduce the reflection of external light from the display device 20, such as by further stacking dam material that transmits the second light L2 in the non-emitting region NLA.

[0162] The second dike BK2 may have a second width W2 in the first direction DR1. In an embodiment, the second width W2 may be less than or equal to the first width W1.

[0163] Since the second thickness TH2 of the first color filter CF1 and the second color filter CF2 can be greater than the first thickness TH1 of the first dam BK1, and the second width W2 of the second dam BK2 can be less than or equal to the first width W1 of the first dam BK1, the first groove H1 can be defined between the first color filter CF1 and the second dam BK2, and the second groove H2 can be defined between the second color filter CF2 and the second dam BK2.

[0164] The first reflection control pattern RCP1 can be arranged in the first groove H1, and the second reflection control pattern RCP2 can be arranged in the second groove H2. For example, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can be formed by inkjet printing.

[0165] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of the reflected light when external light is reflected from the display device 20. The first reflection control pattern RCP1 may include colored ink that corrects the color of the reflected light in the first light-emitting region LA1, and the second reflection control pattern RCP2 may include colored ink that corrects the color of the reflected light in the second light-emitting region LA2. For example, the first reflection control pattern RCP1 may include colored ink that corrects the color of the first light L1 (e.g., red), and the second reflection control pattern RCP2 may include colored ink that corrects the color of the second light L2 (e.g., green). For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may include primary or secondary color ink.

[0166] Since the first reflection control pattern RCP1 and the second reflection control pattern RCP2 are arranged adjacent to the first color filter CF1 and the second color filter CF2, respectively, when external light is reflected from the display device 20, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can affect the color quality of the reflected light. For example, the color quality of the reflected light can be controlled to provide a comfortable color for the user. In addition, since the first reflection control pattern RCP1 and the second reflection control pattern RCP2 respectively include inks that correct the color quality of the first light L1 and the second light L2, the color reproduction of the display device 20 can be improved. Since the third color filter CF3 is omitted at the third light-emitting region LA3, no groove is formed adjacent to the third light-emitting region LA3, and no groove is formed within the embankment opening.

[0167] The outer coating OCL can be arranged on the first color filter CF1 and the second color filter CF2, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2, and the window WM can be arranged on the color filter layer CFL.

[0168] The display device 20 according to embodiments of the present disclosure may include a first dam BK1 disposed in a third light-emitting region LA3 and a non-light-emitting region NLA, and a first reflection control pattern RCP1 and a second reflection control pattern RCP2 disposed in a first groove H1 and a second groove H2 respectively defined between a first color filter CF1 and a second color filter CF2 and a second dam BK2. Reflection from the first dam BK1 can be reduced, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can correct the color quality of the reflected light. Therefore, the reflection of external light from the display device 20 can be reduced, and the color quality of the reflected light from the display device 20 can be improved.

[0169] Furthermore, since the extension of the first embankment BK1 is formed to overlap with the third light-emitting region LA3 and the non-light-emitting region NLA, a separate process for forming a color filter that selectively transmits the third light L3 in the third light-emitting region LA3 is not required. Therefore, the manufacturing process of the display device 20 can be relatively simplified.

[0170] Figure 9 , Figure 10 , Figure 11 and Figure 12 This is an enlarged cross-sectional view illustrating the process in a method of manufacturing (or providing) a display device 20 according to an embodiment of the present disclosure.

[0171] Reference Figure 9 , Figure 10 , Figure 11 and Figure 12 The described method of manufacturing (or providing) the display device 20 may be a manufacturing reference Figure 8 The method of display device 20 is described below. Redundant descriptions will be omitted or simplified in the following text.

[0172] Reference Figure 9 An input sensing layer (ISL) can be formed on the display panel layer (DP).

[0173] A first dam BK1 can be formed on the input sensing layer ISL within the third emitting region LA3 and the non-emitting region NLA. In an embodiment, the first dam BK1 can be formed simultaneously in the third emitting region LA3 and the non-emitting region NLA. The first dam BK1 and the third color filter, which is the portion of the first dam BK1 overlapping with the third emitting region LA3, are in the same layer. In an embodiment, the first dam BK1 extends from the non-emitting region NLA to overlap with the third emitting element LE3 and defines the third color filter. When in the same layer, the elements can be formed using the same process and / or comprise the same material, the elements can be corresponding portions of the same material layer, the elements can be on the same layer by forming an interface with the same lower or upper layer, the elements can be coplanar or disposed with the same thickness, etc., but are not limited thereto. That is, the third color filter and the first dam BK1 are corresponding portions of the same material layer.

[0174] The first embankment BK1 can be formed having a first thickness TH1 in the third direction DR3 and a first width W1 in the first direction DR1. The first width W1 can be the length of the first embankment BK1 in the first direction DR1 in the non-light-emitting region NLA arranged between the first light-emitting region LA1 and the second light-emitting region LA2.

[0175] A first color filter CF1 can be formed on the input sensing layer ISL in the first light-emitting region LA1, and a second color filter CF2 can be formed on the input sensing layer ISL in the second light-emitting region LA2. Since the color filter function of the first embankment BK1, which overlaps with the third light-emitting region LA3, is already in place, the separate color filter CF3 can be omitted.

[0176] In this embodiment, the first color filter CF1, the second color filter CF2, and the first filter BK1 can selectively transmit light of different wavelength bands. The first color filter CF1 can selectively transmit a first light (e.g., Figure 8 The first light L1), and the second color filter CF2 can selectively transmit a second light (e.g., Figure 8 The second light L2), and the first embankment BK1 can selectively transmit the third light (e.g., Figure 8 The third light (L3) can have a color filter function. For example, the first color filter CF1 can selectively transmit light in the red wavelength band, the second color filter CF2 can selectively transmit light in the green wavelength band, and the first filter BK1 can selectively transmit light in the blue wavelength band.

[0177] The first color filter CF1 and the second color filter CF2 can be formed to have a second thickness TH2 on the third-direction DR3. In an embodiment, the second thickness TH2 can be greater than the first thickness TH1.

[0178] Reference Figure 10 A second dam BK2 can be formed on the first dam BK1 in the non-luminescent region NLA. The second dam BK2 can be formed to have a second width W2 in the first direction DR1. The second dam BK2 can selectively transmit the first light. For example, the second dam BK2 can be formed of the same material as the first color filter CF1.

[0179] When the second dam BK2 is formed, a first groove H1 can be formed between the first color filter CF1 and the second dam BK2, and a second groove H2 can be formed between the second color filter CF2 and the second dam BK2. Since there is no separate color filter in the third light-emitting region LA3, no groove is provided at the third light-emitting region LA3.

[0180] Reference Figure 11 and Figure 12 A first reflection control pattern RCP1 can be formed in the first groove H1, and a second reflection control pattern RCP2 can be formed in the second groove H2.

[0181] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of the reflected light. For example, the first reflection control pattern RCP1 can be formed in the first groove H1 by dripping and curing colored ink that corrects the color of the reflected light in the first light-emitting area LA1, and the second reflection control pattern RCP2 can be formed in the second groove H2 by dripping and curing colored ink that corrects the color of the reflected light in the second light-emitting area LA2. For example, the first reflection control pattern RCP1 may be formed by colored ink that corrects red, and the second reflection control pattern RCP2 may be formed by colored ink that corrects green. For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may be formed by ink of a primary color or a secondary color.

[0182] The order in which the first reflection control pattern RCP1 and the second reflection control pattern RCP2 are formed is not limited. For example, by forming the first reflection control pattern RCP1, illuminating the light with external light to observe the reflected light, and then forming the second reflection control pattern RCP2, illuminating the light with external light to observe the reflected light, the color quality of the reflected light can be adjusted. In another example, by forming the second reflection control pattern RCP2, illuminating the light with external light to observe the reflected light, and then forming the first reflection control pattern RCP1, illuminating the light with external light to observe the reflected light, the color quality of the reflected light can be adjusted.

[0183] Return to reference Figure 8 An outer coating OCL can be formed on the first color filter CF1 and the second color filter CF2, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2 to form a color filter layer CFL. A window WM can be formed on the color filter layer CFL, and therefore, it is possible to manufacture... Figure 8 The display device 20 shown in the figure.

[0184] Figure 13 This is an enlarged cross-sectional view showing a display device 21 according to an embodiment of the present disclosure.

[0185] In addition to the second input insulating layer IL2, refer to Figure 13 The described display device 21 can be used with reference to Figure 8 The described display device 20 is substantially the same as or similar to the original. Redundant descriptions will be omitted or simplified in the following text.

[0186] Reference Figure 13The display device 21 may include a first light-emitting region LA1, a second light-emitting region LA2, a third light-emitting region LA3, and a non-light-emitting region NLA. Each of the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 may be a region that emits light, and the non-light-emitting region NLA may be a region that does not emit light.

[0187] In this embodiment, the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can emit light of different wavelength bands. The first light-emitting region LA1 can emit a first light L1, the second light-emitting region LA2 can emit a second light L2, and the third light-emitting region LA3 can emit a third light L3. For example, the first light L1 can be light of the red wavelength band, the second light L2 can be light of the green wavelength band, and the third light L3 can be light of the blue wavelength band, but this disclosure is not limited thereto.

[0188] The display device 21 may include a display panel layer DP, an input sensing layer ISL, a color filter layer CFL, and a window WM.

[0189] The display panel layer DP may include a substrate SUB, a circuit layer DP_CL, a component layer DP_LE, and a package layer TFE. The input sensing layer ISL may be disposed on the display panel layer DP and may include a first conductive layer ICL1, a first input insulating layer IL1, a second conductive layer ICL2, and a second input insulating layer IL2.

[0190] The first conductive layer ICL1 can be arranged in the non-light-emitting area NLA on the display panel layer DP, and can include multiple conductive patterns.

[0191] The first input insulating layer IL1 can be arranged on the first conductive layer ICL1 and can cover the first conductive layer ICL1.

[0192] The second conductive layer ICL2 can be disposed on the first input insulating layer IL1 in the non-light-emitting region NLA, and can include multiple conductive patterns. Some of the multiple conductive patterns of the second conductive layer ICL2 can be connected to the first conductive layer ICL1.

[0193] The second input insulating layer IL2 may be disposed on the first input insulating layer IL1 and the second conductive layer ICL2, and may cover at least a portion of each of the first input insulating layer IL1 and the second conductive layer ICL2.

[0194] In an embodiment, the second input insulating layer IL2 may be disposed in the first light-emitting region LA1 and the second light-emitting region LA2, but may not be disposed in the third light-emitting region LA3. For example, the second input insulating layer IL2 may be disposed in the first light-emitting region LA1 and the second light-emitting region LA2 that emit light with relatively long wavelength bands, but may not be disposed in the third light-emitting region LA3 that emits light with relatively short wavelength bands. Additionally, the second input insulating layer IL2 may be disposed in at least a portion of the non-light-emitting region NLA.

[0195] In this embodiment, the second input insulating layer IL2 may include scattering particles. These scattering particles may be dispersed within the second input insulating layer IL2. The scattering particles can scatter light reflected from the lower component and propagating to the outside, thereby preventing or reducing the visual recognition of color banding caused by reflection. Furthermore, since the scattering particles are not arranged in the third light-emitting region LA3 that emits the third light L3, the reduction in light extraction efficiency of the display device 21 can be minimized.

[0196] although Figure 13 It is shown that the second input insulating layer IL2 is not arranged in the third light-emitting region LA3, but this disclosure is not limited thereto, and in embodiments, the second input insulating layer IL2, which includes scattering particles, may be further arranged in the third light-emitting region LA3.

[0197] The color filter layer CFL can be arranged on the input sensing layer ISL, and can include a first dam BK1, a first color filter CF1, a second color filter CF2, a second dam BK2, a first reflection control pattern RCP1, a second reflection control pattern RCP2, and an outer coating OCL.

[0198] The first barrier BK1 can be arranged on the input sensing layer ISL within the third light-emitting region LA3 and the non-light-emitting region NLA. For example, when the second input insulating layer IL2 does not cover a portion of each of the first input insulating layer IL1 and the second conductive layer ICL2, the first barrier BK1 can cover a portion of each of the first input insulating layer IL1 and the second conductive layer ICL2.

[0199] The first embankment BK1 may have a first width W1 in the first direction DR1 and a first thickness TH1 in the third direction DR3. The first width W1 may be the length of the first embankment BK1 in the first direction DR1 in the non-light-emitting region NLA between the first light-emitting region LA1 and the second light-emitting region LA2, and the first thickness TH1 may be the length of the first embankment BK1 in the third direction DR3 that overlaps with the second input insulating layer IL2 in the plan view.

[0200] In this embodiment, the first barrier BK1 can transmit the third light L3 and can block light with a wavelength band different from that of the third light L3. The first barrier BK1 can selectively transmit light with a relatively short wavelength band.

[0201] A first color filter CF1 can be disposed on the input sensing layer ISL in the first light-emitting region LA1, and a second color filter CF2 can be disposed on the input sensing layer ISL in the second light-emitting region LA2. The first color filter CF1 can selectively transmit a first light L1, and the second color filter CF2 can selectively transmit a second light L2. The first color filter CF1 and the second color filter CF2 can have a second thickness TH2 on the third-direction DR3. In an embodiment, the second thickness TH2 can be greater than the first thickness TH1.

[0202] The second barrier BK2 can be disposed on top of the first barrier BK1 in the non-emitting region NLA. The second barrier BK2 can transmit the first light L1 and can block light with a wavelength band different from that of the first light L1. For example, the second barrier BK2 can be made of the same material as the first color filter CF1.

[0203] Since the first dam BK1, which selectively transmits the third light L3, and the second dam BK2, which selectively transmits the first light L1, are stacked in the non-light-emitting region NLA, the reflection of external light caused by the lower component reflecting the light can be reduced, and color mixing between the first light-emitting region LA1, the second light-emitting region LA2, and the third light-emitting region LA3 can be prevented. Furthermore, reflection from the surface of the first dam BK1 can be reduced, thereby reducing reflection caused by external light from the display device 21.

[0204] The second dike BK2 may have a second width W2 in the first direction DR1. In an embodiment, the second width W2 may be less than or equal to the first width W1.

[0205] Since the second thickness TH2 can be greater than the first thickness TH1, and the second width W2 can be less than or equal to the first width W1, the first groove H1 can be defined between the first color filter CF1 and the second embankment BK2, and the second groove H2 can be defined between the second color filter CF2 and the second embankment BK2.

[0206] The first reflection control pattern RCP1 can be arranged in the first groove H1, and the second reflection control pattern RCP2 can be arranged in the second groove H2.

[0207] In an embodiment, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may have colors that correct the color of the reflected light when external light is reflected from the display device 21. The first reflection control pattern RCP1 may include colored ink that corrects the color of the reflected light in the first light-emitting area LA1, and the second reflection control pattern RCP2 may include colored ink that corrects the color of the reflected light in the second light-emitting area LA2. For example, each of the first reflection control pattern RCP1 and the second reflection control pattern RCP2 may include primary or secondary color ink.

[0208] When external light is reflected from the display device 21, the first reflection control pattern RCP1 and the second reflection control pattern RCP2 can affect the color quality of the reflected light. Furthermore, the color reproduction of the display device 21 can be improved using the first reflection control pattern RCP1 and the second reflection control pattern RCP2.

[0209] The outer coating OCL can be arranged on the first color filter CF1 and the second color filter CF2, the first dam BK1 and the second dam BK2, and the first reflection control pattern RCP1 and the second reflection control pattern RCP2, and the window WM can be arranged on the color filter layer CFL.
