[0003] This disclosure relates to a display device, and more specifically, to a display device including a color conversion panel. Background Technology

[0004] In a light-emitting element, holes supplied from the anode and electrons supplied from the cathode recombine to form excitons in an emitting layer formed between the anode and the cathode, and light is emitted while the excitons are stabilized.

[0005] Because light-emitting elements have various desirable characteristics such as wide viewing angle, fast response speed, thin thickness and low power consumption, they are widely used in various electrical and electronic devices such as televisions, monitors and mobile phones.

[0066] The invention will now be described more fully with reference to the accompanying drawings, in which various embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals throughout denote the same elements.

[0067] The accompanying drawings and description are to be considered illustrative in nature and not restrictive. Throughout the specification, the same reference numerals denote the same elements.

[0068] Furthermore, since the dimensions and thicknesses of each component shown in the accompanying drawings are arbitrarily illustrated for better understanding and ease of description, the invention is not necessarily limited to what is shown. In the drawings, the thicknesses of layers, films, panels, regions, etc., are exaggerated for clarity. Additionally, in the accompanying drawings, the thicknesses of certain layers and regions are exaggerated for better understanding and ease of description.

[0069] It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, the element may be directly on the other element, or there may be intermediate elements present. In contrast, when an element is referred to as being "directly on" another element, there are no intermediate elements present. Furthermore, throughout the specification, the phrase "on" relative to a target element will be understood as being positioned above or below the target element, and need not be understood as being positioned "on the upper side" based on a direction opposite to the direction of gravity.

[0070] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Therefore, without departing from the teachings herein, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part.

[0071] 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 on quantity and are intended to include both the singular and the plural. For example, unless the context clearly indicates otherwise, “element” has the same meaning as “at least one element.” “At least one” is not to 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 be further understood that, when used in this specification, the terms “comprising” and / or “including” or “containing” and / or “having” indicate the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or groups thereof.

[0072] 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 orientation depicted in the drawings, the relative terms are intended to cover different orientations of the device. For example, if the device is flipped in a drawing, an element described as being “below” the other elements will subsequently be oriented to be “above” the other elements. Thus, depending on the specific orientation of the drawing, the term “below” can cover both “below” and “above” orientations. Similarly, if the device is flipped in a drawing, an element described as being “below” or “under” the other elements will subsequently be oriented to be “above” the other elements. Thus, the terms “below” or “under” can cover both “above” and “below” orientations.

[0073] Additionally, throughout the instruction manual, the phrase "in a plane" refers to the target portion viewed from the top, and the phrase "in a cross section" refers to the cross section formed by vertically cutting the target portion viewed from the side.

[0074] In the following, embodiments of the display device according to the present invention will be described in detail with reference to the accompanying drawings.

[0075] Figure 1 This is a schematic top view of the color conversion panel of a display device according to an embodiment of the present invention.

[0076] An embodiment of the display device according to the present invention includes a display panel and a color conversion panel 300, and light emitted from the display panel passes through the color conversion panel to display an image. Figure 1 The configuration of the color filter 230 and the light blocking member 220 is schematically shown in the figure. The color filter 230 includes a first color filter 230R, a second color filter 230G and a third color filter 230B.

[0077] Reference Figure 1 In such an embodiment, the third color filter 230B is positioned on the entire surface of the substrate except for the first opening 231 that overlaps with the first color filter 230R and the second opening 232 that overlaps with the second color filter 230G.

[0078] The first color filter 230R is continuously arranged along the first direction DR1, and the second color filter 230G is also continuously arranged along the first direction DR1. The first color filter 230R and the second color filter 230G may partially overlap at their edges in the second direction DR2.

[0079] Reference Figure 1The area where the first opening 231 of the third color filter 230B and the first color filter 230R overlap will be referred to as the first pixel area PX1, and the area where the second opening 232 of the third color filter 230B and the second color filter 230G overlap will be referred to as the second pixel area PX2. Figure 1 The portion marked by the dashed line will be referred to as the third pixel region PX3. The pixel region defined in this specification is the area on the substrate where the color filter 230 and the color conversion layer (or transmission layer) overlap each other in the vertical direction (or third direction DR3) and emit light outwards.

[0080] The color conversion panel 300 includes light-blocking members 220. The light-blocking members 220 are disposed between the individual pixels. The light-blocking members 220 include a first light-blocking member 220a configured to be parallel to a first direction DR1 and a second light-blocking member 220b configured to be parallel to a second direction DR2 perpendicular to the first direction DR1. Here, the third direction DR3, perpendicular to the plane defined by the first direction DR1 and the second direction DR2, may be the thickness direction of the color conversion panel 300 or the display device.

[0081] The first light-blocking member 220a is positioned between each adjacent pixel region, but the second light-blocking member 220b is positioned only between some adjacent pixel regions. (See reference...) Figure 1 In one embodiment, the second light-blocking member 220b extends from the first light-blocking member 220a disposed between the second pixel region PX2 and the third pixel region PX3, and is disposed on the second direction DR2. In such an embodiment, the second light-blocking member 220b may be disposed between adjacent second pixel regions PX2 on the first direction DR1 and between adjacent third pixel regions PX3 on the first direction DR1.

[0082] The length of the second light-blocking member 220b in the second direction DR2 can be shorter than the length of a pixel region in the second direction DR2. In an embodiment, such as Figure 1 As shown, the second light-blocking member 220b can be connected to the first light-blocking member 220a, but the second light-blocking member 220b can be disposed at a distance from the first light-blocking member 220a. In an embodiment, as... Figure 1 As shown, the second light-blocking member 220b can be configured to be adjacent to the third pixel region PX3 and the second pixel region PX2; however, in other embodiments, the second light-blocking member 220b can be configured in separate regions. Various embodiments will be described in detail later.

[0083] An embodiment of the display device according to the invention includes a second light-blocking member 220b disposed on a second direction DR2, and thus the width of the light-blocking member 220 can be accurately measured during the manufacturing process, thereby facilitating process management.

[0084] In such an embodiment, the second light-blocking member 220b is disposed only in some pixels and is not continuously disposed along the second direction DR2. In such an embodiment, the second light-blocking member 220b is disposed only in some pixels out of all pixels, and is not disposed in all pixels. As will be described in detail later, the second light-blocking member 220b serves as a measuring area for controlling the formation of the width of the first light-blocking member 220a, and the second light-blocking member 220b may be disposed only in 1% to 20% of all pixels.

[0085] In the following, the color conversion panel 300 of the display device according to an embodiment of the present invention will be described in more detail by means of detailed cross-sectional views.

[0086] Figure 2 yes Figure 1 A cross-sectional view taken along line II-II'. Figure 3 yes Figure 1 The cross-sectional view taken along line III-III'. That is to say, Figure 2 It is a cross-sectional view taken along the lines overlapping pixel regions PX1, PX2, and PX3, and Figure 3 It is a cross-sectional view taken along a line that does not overlap with pixel regions PX1, PX2, and PX3.

[0087] In the following text, reference will be made to Figures 1 to 3 An embodiment of a color conversion panel 300 for a display device is described.

[0088] In the embodiments, reference is made to Figure 2 A third color filter 230B is disposed on the color conversion substrate 310. The third color filter 230B is disposed on or covers the entire surface of the color conversion substrate 310 except for the first opening 231 and the second opening 232. The color conversion substrate 310 refers to the substrate constituting the color conversion panel 300. The color conversion substrate 310 may include plastic or glass.

[0089] A third light-blocking member 220c is provided on the third color filter 230B. The third light-blocking member 220c is provided on the third color filter 230B and reduces the reflection of external light by the third color filter 230B.

[0090] In such an embodiment, the first color filter 230R is configured to overlap with the first opening 231. The first color filter 230R may be disposed within or filled within the first opening 231. The first color filter 230R may be configured to partially overlap with the third color filter 230B and the third light-blocking member 220c. Within the first opening 231, the first color filter 230R may directly contact the color conversion substrate 310. (Refer to...) Figure 1 The first color filter 230R can be continuously set along the first direction DR1.

[0091] In such an embodiment, the second color filter 230G is configured to overlap with the second opening 232. The second color filter 230G may be disposed within or fill the second opening 232. The second color filter 230G may be configured to partially overlap with the first color filter 230R, the third color filter 230B, and the third light-blocking member 220c simultaneously. Within the second opening 232, the second color filter 230G may directly contact the color conversion substrate 310. (Refer to...) Figure 1 The second color filter 230G can be continuously set along the first direction DR1.

[0092] The first color filter 230R can be a red color filter, the second color filter 230G can be a green color filter, and the third color filter 230B can be a blue color filter.

[0093] As described, in the embodiment of the display device, instead of the third light-blocking member 220c, the first color filter 230R, the second color filter 230G, and the third color filter 230B directly contact the color conversion substrate 310. Therefore, compared to the case where the light-blocking member is disposed on the color conversion substrate 310 and the color filters are disposed between the light-blocking members, the luminous efficiency can be improved.

[0094] In such an embodiment, since the third light-blocking member 220c is disposed on the third color filter 230B and between each color filter, external light reflection can be reduced.

[0095] In this embodiment, the barrier film 250 is disposed on the first color filter 230R, the second color filter 230G, and the third color filter 230B.

[0096] A first color conversion layer 330R is disposed on the barrier film 250 while overlapping with the first color filter 230R. Additionally, a second color conversion layer 330G is disposed to overlap with the second color filter 230G, and a transmission layer 330B is disposed to overlap with the third color filter 230B. In this embodiment, similar to the first color filter 230R, the first color conversion layer 330R can be continuously disposed along the first direction DR1. The second color conversion layer 330G and the transmission layer 330B can also be continuously disposed along the first direction DR1.

[0097] In one embodiment, the first color conversion layer 330R can convert supplied blue light into red light. In such an embodiment, the first color conversion layer 330R may include a red phosphor, and the red phosphor may be at least one selected from (Ca,Sr,Ba)S, (Ca,Sr,Ba)₂Si₅N₈, CaAlSiN₃, CaMoO₄, and Eu₂Si₅N₈. In another embodiment, the first color conversion layer 330R may include quantum dots. Quantum dots can convert incident blue light into red light.

[0098] The second color conversion layer 330G can convert the supplied blue light into green light. The second color conversion layer 330G may include a green phosphor, and the green phosphor may be selected from yttrium aluminum garnet (YAG), (Ca,Sr,Ba)2, SiO4, SrGa2S4, BAM, α-SiAlON, β-SiAlON, Ca3Sc2Si3O4, etc. 12 Tb3Al5O 12 BaSiO4, CaAlSiON and (Sr 1-x Ba x At least one of Si2O2N2. Here, x can be any number between 0 and 1. In an embodiment, the second color conversion layer 330G may include quantum dots. Quantum dots can convert incident blue light into green light.

[0099] Transmitting layer 330B transmits incident blue light. Transmitting layer 330B may include a transparent polymer, and the supplied blue light is transmitted through transmitting layer 330B and appears blue. Transmitting layer 330B corresponding to the blue emission region includes a material that emits the incident blue light without a separate phosphor or quantum dot, and transmitting layer 330B corresponding to the blue emission region may include a scatterer.

[0100] A light-blocking component 220 is disposed between the first color conversion layer 330R, the second color conversion layer 330G, and the transmissive layer 330B. In an embodiment, as shown... Figure 1As shown, the light blocking member 220 may include a first light blocking member 220a configured to be parallel to the first direction DR1 and a second light blocking member 220b configured to be parallel to the second direction DR2.

[0101] Figure 2 A cross-section including the first light-blocking member 220a is shown. (Refer to...) Figure 2 The first light-blocking member 220a is configured to simultaneously fill the space between the first color conversion layer 330R, the second color conversion layer 330G, and the transmissive layer 330B, which are spaced apart from each other.

[0102] In an embodiment of the manufacturing process of the first color conversion layer 330R, the second color conversion layer 330G, and the transmissive layer 330B, a separation space is provided or formed between each of the color conversion layers 330R and 330G and the transmissive layer 330B, as well as between adjacent color conversion layers 330R and 330G, and the separation space is filled with a first light blocking member 220a.

[0103] In such an embodiment where the first light-blocking member 220a is formed by filling empty spaces, the first light-blocking member 220a may not have a uniform width. That is, the width of the first light-blocking member 220a can change when the separation space between each of the color conversion layers 330R and 330G and the transmission layer 330B, as well as between adjacent color conversion layers 330R and 330G, is changed.

[0104] Therefore, it is desirable to uniformly control and manage the width of the light-blocking member 220 during the process. When the width of the light-blocking member 220 is not properly controlled, color mixing may occur between adjacent color conversion layers 330R and 330G, or between each of the color conversion layers 330R and 330G and the transmission layer 330B. However, as Figure 2 As shown, the width of the first light-blocking member 220a may vary due to the separation space between each of the color conversion layers 330R and 330G and the transmission layer 330B, as well as between adjacent color conversion layers 330R and 330G, and therefore it is difficult to properly control the width of the light-blocking member 220 during the process by using a method for measuring the width of the first light-blocking member 220a.

[0105] In an embodiment of the display device, the second light-blocking member 220b is located in a non-display area, rather than between adjacent color conversion layers 330R and 330G or between each of the color conversion layers 330R and 330G and the transmissive layer 330B. Therefore, the width of the light-blocking member 220 can be controlled by measuring the width of the second light-blocking member 220b, which is formed with a constant width.

[0106] Figure 3 yes Figure 1 A cross-sectional view taken along line III-III'. (Refer to...) Figure 3 The color conversion substrate 310 and the third color filter 230B are in contact with each other. The third light blocking member 220c is disposed on the third color filter 230B, and the first color filter 230R and the second color filter 230G are respectively disposed between adjacent third light blocking members 220c.

[0107] Figure 3 This shows a cross-section of the non-display area, not the pixel area. (See reference) Figure 3 The second light-blocking member 220b is configured to overlap with both the second color conversion layer 330G and the transmission layer 330B.

[0108] In such an embodiment, such as Figure 1 and Figure 3 As shown, the first light-blocking member 220a disposed between the second color conversion layer 330G and the transmissive layer 330B includes a second light-blocking member 220b extending in the second direction DR2 in the non-display area. The second light-blocking member 220b overlaps with the second color conversion layer 330G and the transmissive layer 330B respectively in a direction perpendicular to the color conversion substrate 310 or in a third direction DR3. The width of the light-blocking member 220 can be controlled by measuring the width of the second light-blocking member 220b during the process. Figure 1 and Figure 2 As shown, because the first light-blocking member 220a can be formed simultaneously to fill the space between adjacent color conversion layers 330R and 330G or between each of the color conversion layers 330R and 330G and the transmission layer 330B, the first light-blocking member 220a may have a non-uniform width. In embodiments, as... Figure 1 and Figure 3 As shown, because the second light-blocking member 220b is disposed on a second color conversion layer 330G or a transmissive layer 330B, the second light-blocking member 220b is formed with a constant width, and therefore, the width of the second light-blocking member 220b can be controlled by measurement during the process.

[0109] In this article, width refers to the width measured in the direction perpendicular to the length direction. That is, referring to... Figure 1 The width of the first light blocking member 220a is the width of the first light blocking member 220a measured in the second direction DR2, and the width of the second light blocking member 220b is the width of the second light blocking member 220b measured in the first direction DR1.

[0110] Figure 4 and Figure 5 It is shown Figure 1A photograph of the area of ​​the display device. Figure 4 and Figure 5 In the diagram, the area marked in dark is the region corresponding to the first light-blocking member 220a. (See reference...) Figure 4 and Figure 5 It can be determined that the width of the first light-blocking member 220a is different from the width of the other parallel first light-blocking member 220a. That is, the light-blocking member 220 may shift during the forming process, and therefore, it is not desirable to control the formation of the light-blocking member by measuring the width of the first light-blocking member 220a.

[0111] An embodiment of the display device includes a second light-blocking member 220b, which is disposed on a color conversion layer 330G or a transmissive layer 330B, rather than between adjacent color conversion layers 330R and 330G or between each of the color conversion layers 330R and 330G and the transmissive layer 330B, and thus the formation of the light-blocking member can be controlled by measuring the width of the second light-blocking member 220b.

[0112] As described above, the width of the light-blocking member 220 refers to its width perpendicular to the length direction. That is, the width of the first light-blocking member 220a is its width in the second direction DR2, and the width of the second light-blocking member 220b is its width in the first direction DR1. In this embodiment, the second light-blocking member 220b is a tool used to measure the width of the first light-blocking member 220a, and the widths of the first light-blocking member 220a and the second light-blocking member 220b can be the same.

[0113] Here, "substantially equivalent / equal / identical" means that when considering process distribution, etc., the difference is less than 10%. That is, when the difference between the width of the first light blocking member 220a in the second direction DR2 and the width of the second light blocking member 220b in the first direction DR1 is less than 10%, the width of the first light blocking member 220a and the width of the second light blocking member 220b are considered to be substantially the same as each other.

[0114] Next, an embodiment of the display device including the color conversion panel 300 will be described in detail with reference to the accompanying drawings.

[0115] Figure 6 A cross-section of a display device according to an embodiment of the present invention is shown schematically.

[0116] Reference Figure 6 An embodiment of the display device includes a color conversion panel 300 and a display panel 100. In such an embodiment, the color conversion panel 300 can be compared with the above-mentioned reference. Figures 1 to 5The embodiments of the described color conversion panel are essentially the same.

[0117] In an embodiment, the display panel 100 includes a display substrate 110. A transistor TFT and a first electrode 191 connected to the transistor TFT are disposed on the display substrate 110, and an insulating film 180 is disposed between the first electrode 191 and the display substrate 110.

[0118] The first electrode 191 is connected to the transistor TFT through an opening 185 in the insulating film 180. (Refer to...) Figure 6 A partition wall 350 with an opening is provided in the first electrode 191, a light-emitting element layer 370 is provided in the opening of the partition wall 350, and a second electrode 270 is provided on the partition wall 350 and the light-emitting element layer 370. The light-emitting element layer 370 emits light based on the voltage applied to the first electrode 191 and the second electrode 270.

[0119] The light-emitting element layer 370 emits blue light. The blue light emitted from each light-emitting element layer 370 is converted into red light and green light respectively as it passes through the color conversion layers 330R and 330G, or it is transmitted as blue light in the transmission layer 330B.

[0120] The first electrode 191, the second electrode 270, and the light-emitting element layer 370 together define or form a light-emitting diode (LED).

[0121] An encapsulation layer 390 may be disposed on the second electrode 270. The encapsulation layer 390 may have a multilayer structure including inorganic and organic layers.

[0122] In this embodiment, the configuration of the transistor TFT and the light-emitting diode LED is not limited to... Figure 6 The configuration of the transistor TFT and light-emitting diode LED shown is schematic, but it can include various other transistor TFTs.

[0123] In such an embodiment, as indicated above, the color conversion panel 300 is referenced above. Figures 1 to 3 The description of the color conversion panel 300 is essentially the same, and any repetitive detailed descriptions will be omitted.

[0124] In an embodiment of the display device, blue light emitted from the light-emitting diodes (LEDs) of the display panel 100 passes through the color conversion layers 330R and 330G of the color conversion panel 300 and is converted into red and green light, respectively, or is transmitted as blue light at the transmissive layer 330B, thereby displaying a color image.

[0125] Figure 7 This is a top plan view of the color conversion panel of the display device according to an alternative embodiment. Figure 8 yes Figure 7A cross-sectional view taken along line VIII-VIII'.

[0126] Except that the second light-blocking member 220b is an island-shaped structure separated from the first light-blocking member 220a, Figure 7 and Figure 8 The embodiment of the color conversion panel shown in the figure is similar to Figure 1 The embodiments are basically the same. Figure 7 and Figure 8 The same or similar elements shown above have been used in the description Figure 1 The same reference numerals are used to label the embodiments of the color conversion panel shown in the figures, and any repeated detailed descriptions thereof will be omitted or simplified.

[0127] In an embodiment, such as Figure 7 and Figure 8 As shown, the second light-blocking member 220b is formed as a dot-shaped island, and the forming process of the light-blocking member can be controlled by measuring the width of the second light-blocking member 220b.

[0128] In such an embodiment, when the second light-blocking member 220b is provided as a dot-shaped island, the forming process of other structures can be controlled by measuring the distance between the isolated second light-blocking members 220b.

[0129] In one embodiment, for example, such as Figure 7 and Figure 8 As shown, the distance between a second light-blocking member 220b disposed on a second color conversion layer 330G and a second light-blocking member 220b disposed on another adjacent second color conversion layer 330G (not shown) is measured to determine whether each of the color conversion layers and the transmission layer is formed with an appropriate width.

[0130] In such an embodiment, the distance between the second light-blocking member 220b disposed on the second color conversion layer 330G and the second light-blocking member 220b disposed on the transmissive layer 330B is measured to determine whether each of the color conversion layers and the transmissive layer is formed with an appropriate width.

[0131] Figure 9 This is a top plan view of the color conversion panel of a display device according to another alternative embodiment. Figure 10 yes Figure 9 A cross-sectional view taken along line X-X'.

[0132] Except that the second light-blocking member 220b is a strip with a length in the second direction DR2, Figure 9 and Figure 10 The embodiment of the color conversion panel shown in the figure is similar to Figure 7 The embodiments are basically the same. Figure 9 and Figure 10 The same or similar elements shown above have been used in the description Figure 7 The same reference numerals are used to label the embodiments of the color conversion panel shown in the figures, and any repeated detailed descriptions thereof will be omitted or simplified.

[0133] In an embodiment where the second light-blocking member 220b is strip-shaped, the process stability is increased when the second light-blocking member 220b is formed, and therefore the width of the second light-blocking member 220b can be measured stably.

Figure 11 and Figure 12 The same or similar elements shown above have been used in the description Figure 1 The same reference numerals are used to label the embodiments of the color conversion panel shown in the figures, and any repeated detailed descriptions thereof will be omitted or simplified.

[0136] In such an embodiment, the second light-blocking member 220b may be disposed only on the transmissive layer 330B, and may not be disposed on the first color conversion layer 330R and the second color conversion layer 330G. In this embodiment where the second light-blocking member 220b is disposed only on the transmissive layer 330B, the formation process of the light-blocking member can be controlled by measuring the width of the second light-blocking member 220b. Because only the third color filter 230B is disposed on the bottom surface of the transmissive layer 330B, the top surface of the transmissive layer 330B can have a uniform height. Therefore, the second light-blocking member 220b on the transmissive layer 330B can have a uniform width, and the width of the second light-blocking member 220b can be accurately measured.
