[0066] In this specification, when it is mentioned that a certain component (or region, layer, part, etc.) is "above", "connected" or "combined" with another component, it means that it can be directly arranged on or directly connected / combined with another component, or a third component can be arranged between them.
[0067] The same reference numerals refer to the same constituent elements. Furthermore, in the drawings, the thickness, proportions, and dimensions of the constituent elements are exaggerated for the purpose of effective illustration of the technical content. "And / or" includes more than one combination of the related constituent elements that can be defined.
[0068] The terms "first," "second," etc., can be used to describe multiple constituent elements, but the constituent elements should not be limited by the terms. The terms are used only to distinguish one constituent element from another. For example, without departing from the scope of the invention, a first constituent element can be named a second constituent element, and similarly, a second constituent element can be named a first constituent element. Singular expressions include plural expressions unless the context explicitly indicates a different meaning.
[0069] Furthermore, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are explained based on the directions indicated in the accompanying drawings.
[0070] Terms such as “including” or “having” should be understood as: used to specify the presence of features, figures, steps, operations, constituent elements, components or combinations thereof described in the specification, rather than precluding the presence or possibility of one or more other features or figures, steps, operations, constituent elements, components or combinations thereof.
[0071] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, terms identical to those defined in commonly used dictionaries shall be interpreted as having the same meaning as in the context of the relevant art, and are hereby expressly defined unless interpreted as having an ideal or overly formal meaning.
[0072] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0073] Figures 1a to 1c This is a perspective view of a display device DD according to an embodiment of the present invention.
[0074] like Figures 1a to 1c As shown, the display surface DD-IS is parallel to the surface defined by the first direction axis DR1 and the second direction axis DR2. The normal direction of the display surface DD-IS (i.e., the thickness direction of the display device DD) is indicated by the third direction axis DR3. The front (or upper surface) and back (or lower surface) of each component are divided with reference to the third direction axis DR3. Hereinafter, the directions from the first direction to the third direction, as indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3 respectively, will be referred to with the same reference numerals.
[0075] like Figures 1a to 1c As shown, the display surface DD-IS includes a display area DD-DA for displaying the image IM and a non-display area DD-NDA adjacent to the display area DD-DA. The non-display area DD-NDA is the area where no image is displayed. Figures 1a to 1c An icon image is illustrated as an example of an image IM. As an example, the display area DD-DA can be quadrilateral in shape. The non-display area DD-NDA can surround the display area DD-DA. However, it is not limited to this; the shape of the display area DD-DA and the non-display area DD-NDA can be deformed.
[0076] like Figures 1a to 1c As shown, the display device DD may include multiple regions defined according to the operating mode. The display device DD may include a folded region FA folded based on a folding axis FX, a first planar region NFA1 adjacent to the folded region FA, and a second planar region NFA2. The folded region FA is a region that substantially forms a curvature.
[0077] In this embodiment, a display device DD is illustrated exemplary, having a folding axis FX defined parallel to the major axis of the display device DD. However, this is not a limitation; the folding axis FX may also be parallel to the minor axis of the display device DD. Furthermore, in one embodiment of the invention, the display device DD may also have an unfolded strip shape.
[0078] like Figure 1b As shown, the display device DD can be inner-folded or inner-bending so that the display surface DD-IS of the first planar region NFA1 faces the display surface DD-IS of the second planar region NFA2. Figure 1c As shown, the display device DD can be folded outwards (outer-folding or outer-bending) so that the display surface DD-IS is exposed to the outside. For example... Figures 1a to 1cAs shown, a display module that repeatedly folds and unfolds can be defined as a foldable display module.
[0079] In one embodiment of the present invention, the display device DD may include multiple folding regions FA. Furthermore, the folding regions FA can be defined corresponding to the form in which the user operates the display device DD. For example, the folding regions may also be defined on a plane along a diagonal direction intersecting the first direction axis DR1 and the second direction axis DR2. The area of the folding regions FA is not fixed and can be determined based on the radius of curvature. In one embodiment of the present invention, the display device DD may be configured to repeat only... Figure 1a and Figure 1b The operation mode shown can also be configured to simply repeat... Figure 1a and Figure 1c The operating mode shown.
[0080] This embodiment illustrates a display device DD applied to a portable telephone, but it is not limited thereto. In one embodiment of the invention, the display device DD can be applied to large electronic devices such as televisions and monitors, as well as small and medium-sized electronic devices such as tablet computers, car navigation systems, game consoles, and smartwatches.
[0081] Figures 2a to 2d This is a cross-sectional view of a display device DD according to an embodiment of the present invention. Figures 2a to 2d The diagram illustrates the cross-sections defined by the second directional axis DR2 and the third directional axis DR3. This is to illustrate the stacking relationship of the functional panels and / or functional units constituting the display device. Figures 2a to 2d The display device DD is simply illustrated.
[0082] A display device DD according to an embodiment of the present invention may include a display panel, an input sensor, a reflection prevention unit, and a window. In one embodiment, the input sensor may be omitted. At least a portion of the components of the display panel, the input sensor, the reflection prevention unit, and the window may be formed by a continuous process, or at least a portion of the components may be bonded together by adhesive components. Figures 2a to 2d An exemplary illustration shows a pressure-sensitive adhesive film (PSA) as an adhesive component. The adhesive components described below may include general adhesives or binders and are not particularly limited thereto.
[0083] exist Figures 2a to 2dIn this context, the input sensor, anti-reflection unit, and corresponding components in the window formed with other components through a continuous process are represented as a "layer." The input sensor, anti-reflection unit, and components in the window bonded to other components by adhesive members are represented as a "panel." While a "panel" includes a base layer (e.g., a synthetic resin film, composite film, glass substrate, etc.) providing the substrate, the "layer" may omit the base layer. In other words, a component or unit represented as a "layer" is arranged on a base surface provided by other components or units.
[0084] The input sensor and anti-reflection unit may be referred to as an input sensing panel, anti-reflection panel, or input sensing layer / anti-reflection layer, depending on whether a substrate is present. In this embodiment, all windows are illustrated as using a "panel" type, but it is not limited to this.
[0085] like Figure 2a As shown, the display device DD may include a display panel DP, an input sensing layer ISL, a reflection prevention panel RPP, and a window WP. In the display device DD, the combined structure other than the window WP can be defined as a display module.
[0086] The input sensing layer ISL is directly disposed on the display panel DP. In this specification, "B1 configuration is directly disposed on A1 configuration" means that no adhesive components are disposed between A1 configuration and B1 configuration. After A1 configuration is formed, B1 configuration is formed on the base surface provided by A1 configuration through a continuous process. Pressure-sensitive adhesive films PSA are disposed between the anti-reflective panel RPP and the window WP, and between the input sensing layer ISL and the anti-reflective panel RPP, respectively.
[0087] The display panel (DP) generates an image, and the input sensing layer (ISL) acquires the coordinate information of external inputs (e.g., touch events). Although not illustrated separately, a protective component may also be arranged on the underside of the display panel (DP). This protective component supports the display panel (DP) and protects it from external impacts.
[0088] According to an embodiment of the present invention, the display panel DP can be a light-emitting display panel and is not particularly limited thereto. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of an organic light-emitting display panel may include an organic light-emitting material. The light-emitting layer of a quantum dot light-emitting display panel may include quantum dots and / or quantum rods, etc. Hereinafter, the display panel DP is described as an organic light-emitting display panel.
[0089] The anti-reflection panel RPP reduces the reflectivity of natural light (or sunlight) incident from the upper side of the window WP. According to an embodiment of the invention, the anti-reflection panel RPP includes a base layer and color filters. The color filters have a predetermined arrangement. The arrangement of the color filters can be determined taking into account the emission colors of the pixels included in the display panel DP. The anti-reflection panel RPP may also include a black matrix adjacent to the color filters.
[0090] According to one embodiment of the present invention, the window WP may include a base layer WP-BS and a light-blocking pattern WP-BZ. The base layer WP-BS may have a multi-layer structure. The base layer WP-BS may include a glass substrate and / or a synthetic resin film, etc.
[0091] The light-blocking pattern WP-BZ partially overlaps with the substrate WP-BS. The light-blocking pattern WP-BZ can be arranged on the back of the substrate WP-BS to define the bezel area of the display device DD (i.e., the non-display area DD-NDA, see Figure 1). The light-blocking pattern WP-BZ is a colored organic film, which can be formed, for example, by coating. Figures 2b to 2d In the diagram, the window WP does not distinguish between the base layer WP-BS and the light-blocking pattern WP-BZ, thus simplifying the illustration.
[0092] In one embodiment of the present invention, the light-blocking pattern WP-BZ may be omitted. In one embodiment of the present invention, the light-blocking pattern WP-BZ may be disposed on the anti-reflection panel RPP. In one embodiment of the present invention, the light-blocking pattern WP-BZ may be disposed on other optical components or other synthetic resin films and disposed on the lower side of the window WP.
[0093] like Figure 2b and Figure 2c As shown, the display device DD may include a display panel DP, a reflection-prevention panel RPP, an input sensing panel ISP, and a window WP. The stacking order of the input sensing panel ISP and the reflection-prevention panel RPP can be changed.
[0094] like Figure 2d As shown, the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection layer RPL, and a window WP. Most of the bonding components can be omitted from the display device DD. The input sensing layer ISL and the anti-reflection layer RPL are formed on the substrate provided by the display panel DP through a continuous process. The stacking order of the input sensing layer ISL and the anti-reflection layer RPL can be changed.
[0095] In one embodiment of the invention, the anti-reflection layer RPL may include a color filter. A detailed description of the anti-reflection layer RPL will follow.
[0096] Figure 3 This is a plan view of the display area DD-DA according to an embodiment of the present invention.
[0097] Reference Figure 3 Multiple luminescent regions PXA-R, PXA-G1, PXA-G2, and PXA-B are arranged within the display area DD-DA. A surrounding area NPXA is arranged adjacent to these luminescent regions. The surrounding area NPXA defines the boundaries of the luminescent regions PXA-R, PXA-G1, PXA-G2, and PXA-B, and prevents color mixing between them. The multiple luminescent regions PXA-R, PXA-G1, PXA-G2, and PXA-B can define multiple pixel rows PXL-1 and PXL-2 extending along the second direction DR2. Figure 3 In this context, the second direction DR2 is defined as the extension direction (or row direction) of pixel rows PXL-1 and PXL-2, and the first direction DR1 is defined as the column direction.
[0098] In this embodiment, the multiple pixel rows PXL-1 and PXL-2 can be divided into two groups. The first group of pixel rows PXL-1 includes a first color light-emitting region (hereinafter, first color region) PXA-R that generates a first color light and a second color light-emitting region (hereinafter, second color region) PXA-B that generates a second color light. The first color region PXA-R and the second color region PXA-B are arranged alternately along the row direction DR2. The first group of pixel rows PXL-1 can include a first pixel row PXL-11 and a second pixel row PXL-12. The first pixel row PXL-11 and the second pixel row PXL-12 can be arranged alternately along the column direction DR1.
[0099] For the first pixel row PXL-11 and the second pixel row PXL-12, the arrangement order of the first color region PXA-R and the second color region PXA-B is different from each other. Within the column direction DR1, the first color region PXA-R of the first pixel row PXL-11 and the second color region PXA-B of the second pixel row PXL-12 can be aligned, and the second color region PXA-B of the first pixel row PXL-11 and the first color region PXA-R of the second pixel row PXL-12 can be aligned.
[0100] The second group of pixel rows PXL-2 may include third-color emitting regions (hereinafter, third-color regions) PXA-G1 and PXA-G2 that generate third-color light. The third-color regions PXA-G1 and PXA-G2 can be divided into two types of emitting regions with different shapes on the plane. If the first type region PXA-G1 is rotated 90 degrees on the plane, it can have the same shape as the second type region PXA-G2. The first type region PXA-G1 can have a shape extending along a first intersecting direction DDR1, and the second type region PXA-G2 can have a shape extending along a second intersecting direction DDR2, which is orthogonal to the first intersecting direction DDR1.
[0101] The first type of region PXA-G1 and the second type of region PXA-G2 are arranged alternately along the row direction DR2. The second group of pixel rows PXL-2 may include a third pixel row PXL-21 and a fourth pixel row PXL-22. The third pixel row PXL-21 and the fourth pixel row PXL-22 may be arranged alternately along the column direction DR1.
[0102] For the third pixel row PXL-21 and the fourth pixel row PXL-22, the arrangement order of the first type region PXA-G1 and the second type region PXA-G2 is different from each other. Within column direction DR1, the first type region PXA-G1 of the third pixel row PXL-21 and the second type region PXA-G2 of the fourth pixel row PXL-22 can be aligned, and the second type region PXA-G2 of the third pixel row PXL-21 and the first type region PXA-G1 of the fourth pixel row PXL-22 can be aligned. However, this is not a limitation; the second group of pixel rows PXL-2 may also include only one type of luminous region whose shape is the same on the plane.
[0103] The first group of pixel rows PXL-1 and the second group of pixel rows PXL-2 can be arranged alternately along the column direction DR1. One of the third pixel rows PXL-21 and the fourth pixel row PXL-22 is arranged between the consecutive first pixel rows PXL-11 and the second pixel rows PXL-12, and the other of the third pixel rows PXL-21 and the fourth pixel rows PXL-22 is arranged between the second pixel row PXL-12 and another consecutive first pixel row PXL-11.
[0104] In this embodiment, illuminating regions PXA-R (first color), PXA-B (second color), and PXA-G1 and PXA-G2 (third color) with different areas on a plane are illustrated, but the embodiment is not limited thereto. Although the illustration shows the second color emitting region PXA-B with the largest area and the third color emitting regions PXA-G1 and PXA-G2 with the smallest area, this is merely an example.
[0105] In this embodiment, the first-color emitting region PXA-R generates red light, the second-color emitting region PXA-B generates blue light, and the third-color emitting regions PXA-G1 and PXA-G2 generate green light. However, it is not limited to this. The colored light emitted by the first-color emitting region PXA-R, the second-color emitting region PXA-B, and the third-color emitting regions PXA-G1 and PXA-G2 can be selected from a combination of three colored lights that can generate white light by mixing the emitted colored lights.
[0106] like Figure 3 As shown, the number of third color regions PXA-G1 and PXA-G2 is greater than the number of each of the first color regions PXA-R and the second color regions PXA-B (approximately twice the number), therefore the reflected light reflected in the display areas DD-DA can have predetermined characteristics. In particular, when the display device DD (see Figure 1) is off, the black reflected light can have a predetermined color perception. The reflected light is external light (e.g., natural light) reflected in the display areas DD-DA.
[0107] Even due to reference Figures 2a to 2d The aforementioned anti-reflection units RPP and RPL reduce reflectivity, allowing the reflected light to retain predetermined color characteristics. According to this embodiment, even if the emitting regions PXA-R, PXA-G1, PXA-G2, and PXA-B have a reference... Figure 3 With the aforementioned arrangement, the color perception of the reflected light can also approach that of pure black. Compared to a comparative example that includes a polarizing plate as a reflection prevention unit, the color shift of the reflected light can be minimal for the display device according to this embodiment. This will be explained in detail below with reference to the relationship between the light-emitting regions PXA-R, PXA-G1, PXA-G2, PXA-B and the reflection prevention units RPP, RPL.
[0108] Figure 4 It is based on Figure 3 A sectional view of I-I'. Figure 4 The specific illustration is as follows. Figures 2a to 2d The aforementioned display panel DP.
[0109] The display panel (DP) may include a base layer (BL), a circuit element layer (DP-CL), a display element layer (DP-OLED), and an upper insulating layer (TFL). The stacked structure of the display panel (DP) is not particularly limited.
[0110] Reference Figure 4 The display panel (DP) can include multiple insulating layers, semiconductor patterns, conductive patterns, signal lines, etc. The insulating, semiconductor, and conductive layers are formed through methods such as coating and deposition. Subsequently, the insulating, semiconductor, and conductive layers can be selectively patterned using photolithography. In this way, semiconductor patterns, conductive patterns, signal lines, etc., are formed in both the circuit element layer (DP-CL) and the display element layer (DP-OLED).
[0111] The substrate BL can include a synthetic resin film. In addition, the substrate BL can include a glass substrate, a metal substrate, or an organic / inorganic composite material substrate, etc.
[0112] At least one inorganic layer is disposed on the upper surface of the substrate BL. The buffer layer BFL improves the adhesion between the substrate BL and the semiconductor pattern.

Figure 3 Semiconductor patterns can also be arranged on it. Semiconductor patterns can be distributed across multiple light-emitting areas PXA-R, PXA-G1, PXA-G2, PXA-B (see reference). Figure 3 Semiconductor patterns are arranged according to specific rules. The electrical properties of semiconductor patterns differ depending on doping characteristics such as whether or not they are doped. Semiconductor patterns can include doped and undoped regions. Doped regions can be doped with N-type or P-type dopants. A P-type transistor includes a doped region doped with P-type dopants.
[0115] The conductivity of doped regions is greater than that of undoped regions, and they essentially function as electrodes or signal lines. Undoped regions are essentially equivalent to the active region (or channel) of a transistor. In other words, a portion of a semiconductor pattern can be the active region of a transistor, another portion can be the source or drain of a transistor, and yet another portion can be a connecting electrode or a connecting signal line.
[0116] like Figure 4As shown, the source S1, active region A1, and drain D1 of transistor T1 are formed from a semiconductor pattern. Figure 4 A portion of the connection signal line SCL, formed from a semiconductor pattern, is illustrated. Although not shown separately, the connection signal line SCL can be connected in a plane to the drain D1 of transistor T1.

[0120] Figure 4 The diagram illustrates the luminescent region PXA and the surrounding region (or non-luminescent region) NPXA adjacent to the luminescent region PXA. Essentially, the luminescent region PXA can be defined as a portion of the area of the first electrode AE exposed through the luminescent opening OP.
[0121] A hole control layer (HCL) can be arranged together in the light-emitting region PXA and the surrounding region NPXA. The hole control layer HCL may include a hole transport layer and may also include a hole injection layer. A light-emitting layer (EML) is arranged on the hole control layer HCL. The EML may be arranged in the region corresponding to the light-emitting opening OP. That is, the EML may be formed separately in each of the light-emitting regions PXA-R, PXA-G1, PXA-G2, and PXA-B.
[0122] An electron control layer (ECL) is disposed on the light-emitting layer (EML). The ECL may include an electron transport layer and may also include an electron injection layer. A second electrode (CE) is disposed on the ECL.
[0123] An upper insulating layer TFL is disposed on the second electrode CE. The upper insulating layer TFL may include multiple thin films. As in this embodiment, the upper insulating layer TFL may include a capping layer and a thin film encapsulation layer.
[0124] Figure 5 It is based on Figure 3 Sectional view of II-II'. Figure 5 A simplified illustration of the display panel (DP) is provided, centered on the three types of luminous areas: PXA-R, PXA-G1, and PXA-B. Furthermore, Figure 5 by Figure 2d The diagram is enlarged based on the reference point.
[0125] First electrodes AE-R, AE-B, and AE-G1, corresponding to the first color region PXA-R, the second color region PXA-B, and the third color region PXA-G1, are arranged on the circuit element layer DP-CL. Light-emitting openings OP-R, OP-B, and OP-G1, corresponding to the first color region PXA-R, the second color region PXA-B, and the third color region PXA-G1, are defined on the pixel definition film PDL. Figure 5 In China, the light-emitting element OLED (refer to...) Figure 4 A portion of the composition is not shown in the diagram.
[0126] Reference Figure 5 The input sensing layer ISL can be directly disposed on the upper insulating layer TFL. The input sensing layer ISL may include a first insulating layer IS-IL1, a first conductive layer IS-CL1, a second insulating layer IS-IL2, a second conductive layer IS-CL2, and a third insulating layer IS-IL3. In one embodiment of the present invention, the first insulating layer IS-IL1 and / or the third insulating layer IS-IL3 may be omitted.
[0127] Each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 can have a single-layer structure or a multilayer structure stacked along a third directional axis DR3. The multilayer conductive layer can include at least two of a transparent conductive layer and a metal layer. The multilayer conductive layer can include metal layers containing different metals. The transparent conductive layer can include indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium tin zinc oxide (ITZO), poly(ethylenedioxythiophene) (PEDOT), metal nanowires, and graphene. The metal layer can include molybdenum, silver, titanium, copper, aluminum, and alloys thereof. For example, each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 can have a three-layer metal layer structure, such as a titanium / aluminum / titanium three-layer structure. Relatively durable and low-reflectivity metals can be used in the upper / lower layers, while a more conductive metal can be used in the inner layers.
[0128] Each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 includes multiple conductive patterns. The following description assumes that the first conductive layer IS-CL1 includes a first conductive pattern and the second conductive layer IS-CL2 includes a second conductive pattern. Each of the first and second conductive patterns may include a sensing electrode and a signal line connected thereto. The first and second conductive patterns may be arranged to overlap with the dividing pattern BM, which will be described later. The dividing pattern BM prevents external light reflection caused by the first and second conductive patterns.
[0129] Each of the first insulating layer IS-IL1 to the third insulating layer IS-IL3 may include an inorganic film or an organic film. In this embodiment, the first insulating layer IS-IL1 and the second insulating layer IS-IL2 may be inorganic films. The third insulating layer IS-IL3 may include an organic film.
[0130] Reference Figure 5 The anti-reflection layer RPL can be directly disposed on the input sensing layer ISL. The anti-reflection layer RPL may include a dividing pattern BM and a first color filter CF-R, a second color filter CF-B, and a third color filter CF-G1.
[0131] The dividing pattern BM overlaps with the surrounding area NPXA. The dividing pattern BM is a pattern with black color and may include a light-blocking pattern. In one embodiment, the dividing pattern BM may include a black coloring agent. The black coloring agent may include black dye or black pigment. The black coloring agent may include carbon black, a metal such as chromium, or an oxide thereof.
[0132] The dividing pattern BM is defined with openings OP-BR, OP-BB, and OP-BG1 corresponding to openings OP-R, OP-B, and OP-G1, respectively. The opening areas of the openings OP-BR, OP-BB, and OP-BG1 in the dividing pattern BM are larger than the opening areas of the corresponding openings OP-R, OP-B, and OP-G1 in the pixel-defined film PDL.
[0133] The first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1 correspond to the first color region PXA-R, the second color region PXA-B, and the third color region PXA-G1, respectively. The first color filter CF-R allows the first color light (i.e., red light) to pass through, the second color filter CF-B allows the second color light (i.e., blue light) to pass through, and the third color filter CF-G1 allows the third color light (i.e., green light) to pass through.
[0134] The first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1 reduce the reflectivity of external light. Each of the first color filters CF-R to the third color filter CF-G1 allows light within a specific wavelength range to pass through and absorbs light outside the corresponding wavelength, thus absorbing most of the natural light and reflecting only a portion of it.
[0135] The first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1 comprise a matrix resin and dyes and / or pigments dispersed in the matrix resin. The matrix resin, as the medium in which the dyes and / or pigments are dispersed, can be composed of various resin compositions commonly referred to as binders.
[0136] The anti-reflection layer RPL may include a protective layer OCL covering the first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1. The protective layer OCL comprises an organic material and may provide a flat surface. In one embodiment, the protective layer OCL may be omitted.
[0137] A portion of the first color filter CF-R, a portion of the second color filter CF-B, and a portion of the third color filter CF-G1, arranged within the surrounding area NPXA, are respectively arranged on the dividing pattern BM. In this embodiment, the dividing pattern BM is illustrated as being arranged lower than the first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1, but it is not limited thereto. In one embodiment, the dividing pattern BM may also be arranged above at least one of the first color filter CF-R, the second color filter CF-B, and the third color filter CF-G1.
[0138] At least one of the first color filter CF-R and the second color filter CF-B is arranged on the third color filter CF-G1. For example... Figure 5As shown, a portion of the first color filter CF-R is positioned on top of the third color filter CF-G1 within the area where the dividing pattern BM is arranged. The second color filter CF-B can also be positioned on top of the third color filter CF-G1, partially covering it. The first color filter CF-R and the second color filter CF-B can adjust the exposed area of the third color filter CF-G1 to regulate the color perception of the reflected light. This will be explained in detail below.
[0139] Figures 6a to 6e This is a plan view illustrating the manufacturing process of a reflection prevention unit according to an embodiment of the present invention. Figures 6a to 6e Enlarged image Figure 3 A portion of the area. The manufacturing process is described in detail, centered on the six light-emitting regions PXA-R1, PXA-R2, PXA-B1, PXA-B2, PXA-G1, and PXA-G2 of the first pixel row PXL-11, the second pixel row PXL-12, and the third pixel row PXL-21 arranged between them.
[0140] Reference Figure 6a The diagram illustrates the first and fourth emitting regions PXA-R1 and PXA-R2 that generate red light, the second and third emitting regions PXA-B1 and PXA-B2 that generate blue light, and the fifth and sixth emitting regions PXA-G1 and PXA-G2 that generate green light. The fifth emitting region PXA-G1 is located inside the area defined by the first, second, third, and fourth emitting regions PXA-R1, PXA-B1, and PXA-B2.
[0141] The first luminous region PXA-R1 and the second luminous region PXA-B1 are included in the first pixel row PXL-11, and the third luminous region PXA-B2 and the fourth luminous region PXA-R2 are included in the second pixel row PXL-12. The fifth luminous region PXA-G1 and the sixth luminous region PXA-G2 are included in the third pixel row PXL-21.
[0142] like Figure 6b As shown, a segmentation pattern BM is formed. This can be achieved... Figure 5 The dividing pattern BM is directly formed on the input sensing layer ISL shown. After forming a resin layer including a matrix resin and a black component, a first opening OP-BR1, a second opening OP-BR2, a third opening OP-BB1, a fourth opening OP-BB2, a fifth opening OP-BG1, and a sixth opening OP-BG2 are formed on the resin layer by photolithography.
[0143] like Figure 6cAs shown, third color filters CF-G1 and CF-G2 are formed corresponding to the fifth luminous region PXA-G1 and the sixth luminous region PXA-G2, respectively. The third color filter CF-G1 corresponding to the fifth luminous region PXA-G1 and the third color filter CF-G2 corresponding to the sixth luminous region PXA-G2 can be separated from each other.
[0144] In such Figure 5 After the color filter layer is formed on the input sensing layer ISL shown, the color filter layer is patterned by photolithography. In one embodiment of the present invention, the third color filter CF-G1 corresponding to the fifth light-emitting region PXA-G1 and the third color filter CF-G2 corresponding to the sixth light-emitting region PXA-G2 can also be patterned into a single shape.
[0145] The following explanation focuses on the third color filter CF-G1, which corresponds to the fifth luminous region PXA-G1. The edge of the third color filter CF-G1 may overlap with the dividing pattern BM.
[0146] like Figure 6d As shown, second color filters CF-B1 and CF-B2 are formed corresponding to the second luminous region PXA-B1 and the third luminous region PXA-B2. In... Figure 5 After the color filter layer is formed on the input sensing layer ISL shown, the color filter layer is patterned by photolithography. Figure 6d The illustration shows the patterns (or, color filter patterns) CF-B1 corresponding to the second light-emitting area PXA-B1 and CF-B2 corresponding to the third light-emitting area PXA-B2.
[0147] The portions of the second color filters CF-B1 and CF-B2 that overlap with the dividing pattern BM are arranged on the third color filter CF-G1. This is not limited to the case where the entire overlapping portion of the second color filters CF-B1 and CF-B2 with the dividing pattern BM is arranged on the third color filter CF-G1. It is sufficient if a portion of the overlapping portion of the second color filters CF-B1 and CF-B2 with the dividing pattern BM is arranged on the third color filter CF-G1.
[0148] In one embodiment, the second color filters CF-B1 and CF-B2 may not be distinguished as multiple patterns, but have a single shape. Although not shown separately, the color filters corresponding to the emitting areas that generate blue light can be formed by a single process.
[0149] like Figure 6eAs shown, first color filters CF-R1 and CF-R2 are formed corresponding to the first light-emitting region PXA-R1 and the fourth light-emitting region PXA-R2. A portion of the first color filters CF-R1 and CF-R2 that overlaps with the dividing pattern BM overlaps with the third color filter CF-G1. It is not limited to the case where the entire portion of the first color filters CF-R1 and CF-R2 that overlaps with the dividing pattern BM is arranged on the third color filter CF-G1. It is sufficient that a portion of the portion of the first color filters CF-R1 and CF-R2 that overlaps with the dividing pattern BM is arranged on the third color filter CF-G1.
[0150] In one embodiment, the first color filters CF-R1 and CF-R2 may not be distinguished as multiple patterns, but have a single shape. Although not shown separately, the color filters corresponding to the emitting areas that generate red light can be formed by a single process. In the above description, the first color filters CF-R1 and CF-R2 are formed after the second color filters CF-B1 and CF-B2, but this is not a limitation. The formation order can be changed.
[0151] Reference Figure 6e The first color filters CF-R1 and CF-R2, and the second color filters CF-B1 and CF-B2 cover a portion of the third color filter CF-G1 within the surrounding area NPXA. Accordingly, when viewed on a plan view, the exposed area of the third color filter CF-G1 is reduced.
[0152] For reference Figure 3 As stated above, since the number of third color regions PXA-G1 and PXA-G2 is greater than the number of first color regions PXA-R and second color regions PXA-B, the number of patterns in the third color filters CF-G1 and CF-G2 is greater than the number of patterns in the first color filters CF-R1 and CF-R2 and the second color filters CF-B1 and CF-B2. When comparing the occupied area, the area of the third color filters CF-G1 and CF-G2 is greater than the area of the first color filters CF-R1 and CF-R2 and the second color filters CF-B1 and CF-B2.
[0153] Therefore, as described above, by reducing the exposed area of the third color filter CF-G1, the deviation in the exposed areas of the first color filters CF-R1, CF-R2, the second color filters CF-B1, CF-B2, and the third color filters CF-G1, CF-G2 can be reduced when viewed on a plan view. As a result, the perceived color of black can be prevented from transforming into a specific color.
[0154] Figure 7a and Figure 7b This is a plan view of the display area DD-DA according to an embodiment of the present invention. Figure 7c and Figure 7d It is based on Figure 7a Sectional view of III-III'. Figure 8 This is a plan view of the display area DD-DA according to an embodiment of the present invention. Figure 7a Corresponding to Figure 6e The following will omit references or references. Figures 3 to 6e The following is a detailed description of the same structure.
[0155] like Figure 7a As shown, the first color filter CF-R, which corresponds to the first light-emitting region PXA-R1 and the fourth light-emitting region PXA-R2, can have an integral shape.
[0156] The first color filter CF-R has an opening (hereinafter, the color opening) OP-CR that corresponds to the fifth light-emitting area PXA-G1 and exposes the third color filter CF-G1. Figure 7b by Figure 3 The shape of the first color filter CF-R is illustrated as a reference diagram. Figure 7b A first color filter CF-R can be formed with an integral shape for multiple light-emitting areas PXA-R, PXA-G1, PXA-G2, and PXA-B. The first color filter CF-R defines a color opening OP-CR1 corresponding to the second color area PXA-B and a color opening OP-CR2 corresponding to the third color areas PXA-G1 and PXA-G2.
[0157] Refer again Figure 7a The color opening OP-CR has an area larger than that of the fifth light-emitting region PXA-G1, and also has an area larger than that of the fifth opening OP-BG1. The first color filter CF-R may include a first portion P1 corresponding to the first light-emitting region PXA-R1, a second portion P2 corresponding to the fourth light-emitting region PXA-R2, and a first bridging portion P3 and a second bridging portion P4 extending from the first portion P1 to the second portion P2. (The last sentence appears to be incomplete and possibly refers to a different context.) Figure 6e As shown, the first color filter CF-R surrounds the fifth opening OP-BG1. The first bridging portion P3 and the second bridging portion P4 are arranged between the edge of the dividing pattern BM that defines the fifth opening OP-BG1 and the second color filter CF-B.
[0158] like Figure 7cAs shown, within the surrounding region NPXA, a portion of the third color filter CF-G1 can be arranged on portions of the second color filters CF-B1 and CF-B2, respectively. The third color filter CF-G1 is formed after the second color filters CF-B1 and CF-B2 are formed. Within the surrounding region NPXA, portions of the first bridging portion P3 and the second bridging portion P4 can be arranged on portions of the second color filters CF-B1 and CF-B2, respectively. Within the surrounding region NPXA, portions of the first bridging portion P3 and the second bridging portion P4 can be arranged on the third color filter CF-G1, respectively. On the dividing pattern BM, portions of the first color filter CF-R, portions of the second color filters CF-B1 and CF-B2, and portions of the third color filter CF-G1 all overlap.
[0159] The order in which the second color filters CF-B1 and CF-B2 are formed, and the third color filter CF-G1, is not limited to this. For example... Figure 7d As shown, within the surrounding area NPXA, portions of the second color filters CF-B1 and CF-B2 can be arranged on portions of the third color filter CF-G1, respectively.
[0160] according to Figure 8 As shown, with Figures 7a to 7d Unlike the diagram, within the surrounding area NPXA, a portion of the first bridging portion P3 and a portion of the second bridging portion P4 may not overlap with the second color filters CF-B1 and CF-B2. One of the two second color filters CF-B1 and CF-B2 can be a side color filter (or, the first color filter pattern) CF-B1, and the other is defined as the other side color filter (or, the second color filter pattern) CF-B2.
[0161] On the plane, the first bridging portion P3 can be separated from one side color filter CF-B1, and the second bridging portion P4 can be separated from the other side color filter CF-B2. Through the separated areas, a portion of the third color filter CF-G1 arranged below the first color filter CF-R and the second color filters CF-B1 and CF-B2 can be exposed.
[0162] Figure 9 This is a plan view of the display area DD-DA according to an embodiment of the present invention. Figure 9 Corresponding to Figure 7a The following is for reference. Figures 7a to 8 The explanation focuses on the different compositions described above.
[0163] According to this embodiment, the second color filter CF-B, corresponding to the second light-emitting region PXA-B1 and the third light-emitting region PXA-B2, can have an integral shape. A color opening OP-CB is defined in the second color filter CF-B, corresponding to the fifth light-emitting region PXA-G1 and exposing the third color filter CF-G1.
[0164] Although not illustrated separately, the second color filter CF-B can be defined with respect to the first color region PXA-R (see reference). Figure 3 The corresponding colored opening and the colored opening corresponding to the third color areas PXA-G1 and PXA-G2.
[0165] A portion of the second color filter CF-B that overlaps with the dividing pattern BM covers a portion of the third color filter CF-G1. The second color filter CF-B may include a first bridging portion P3 and a second bridging portion P4. Although the first bridging portion P3 and the second bridging portion P4 are illustrated to overlap with the first color filters CF-R1 and CF-R2, this is not a limitation. The stacking order of the second color filter CF-B with the first color filters CF-R1 and CF-R2 is not restricted.
[0166] Although the above description has been made with reference to preferred embodiments of the present invention, it will be understood by those skilled in the art or those with ordinary knowledge of the art that various modifications and alterations can be made to the present invention without departing from the spirit and technical scope of the invention as set forth in the claims.
[0167] Therefore, the technical scope of this invention should not be limited to the contents described in the detailed specification, but should be determined by the scope of the claims.
