[0051] <First Exemplary Embodiment>

[0052] Figure 1 and Figure 2 are plan views schematically showing an arrangement of sub-pixels and an arrangement of color filter patterns of a light emitting display device according to a first exemplary embodiment of the present invention, respectively. Figure 3 and Figure 4 Amplify Figure 1 and Figure 2 View of area A.

[0053] Figure 5 It is along Figure 3 A cross-sectional view taken along line V-V'. Figure 6 It is along Figure 3 A cross-sectional view taken along line VI-VI'. Figure 7 It is along Figure 3 A cross-sectional view taken along line VII-VII'.

[0054] Before a detailed description, the light emitting display device 10 according to the exemplary embodiment of the present invention may be any of all types of display devices that display images using (organic or inorganic) light emitting diodes OD as self-luminous light emitting elements.

[0055] In this exemplary embodiment, for convenience of description, an organic light emitting display device is used as the light emitting display device 10 as an example, but the embodiment is not limited thereto.

[0056] Furthermore, as an example, the light-emitting display device 10 may be a display device in a VR, AR, or MR-based electronic device for displaying a virtual image or a mixture of a virtual image and an external real image, but is not limited thereto.

[0057] In addition, the light-emitting display device 10 may be a top-emitting display device, a bottom-emitting display device, or a dual-emitting display device. In this exemplary embodiment, for convenience of description, the top-emitting display device 10 is taken as an example.

[0058] Reference Figures 1 to 7 The light-emitting display device 10 of this exemplary embodiment may include a display area (or active area) AA displaying an image and a non-display area (or inactive area) NA located outside the display area AA and partially or completely surrounding the display area AA.

[0059] In the display area AA, a plurality of sub-pixels SP for displaying an image may be arranged along a plurality of row lines (or horizontal lines) and column lines (or vertical lines) on the substrate 101. At the same time, a plurality of gate lines extending in a horizontal direction (or a first direction) as a row direction, and a plurality of data lines extending in a vertical direction (or a second direction) as a column direction may be formed on the substrate 101. Each sub-pixel SP may be connected to a corresponding gate line and a data line. Embodiments are not limited thereto. As an example, a plurality of gate lines may extend in a vertical direction, and a plurality of data lines may extend in a horizontal direction. As an example, a plurality of sub-pixels SP for displaying an image may be arranged in directions other than row lines and column lines, but are not limited thereto.

[0060] Here, as an example, a plurality of sub-pixels SP may include sub-pixels constituting a unit pixel for displaying a color image and respectively displaying a first color, a second color, and a third color as different colors for realizing white. For example, a plurality of sub-pixels SP may include a red (R) sub-pixel SPr, a green (G) sub-pixel SPg, and a blue (B) sub-pixel SPb that respectively display red (R), green (G), and blue (B). Embodiments are not limited thereto. As an example, a plurality of sub-pixels SP may include sub-pixels that respectively display three or more colors as different colors for realizing white or colors other than white. As an example, a white sub-pixel that displays white may also be included. As an example, sub-pixels that display other colors such as cyan, magenta, or yellow may be additionally or alternatively included.

[0061] Each sub-pixel (SP) may include a light emitting diode (OD) as a light emitting element. In addition, the sub-pixel SP may include a plurality of thin film transistors TR and at least one capacitor as a driving circuit for driving the light emitting diode OD.

[0062] Meanwhile, in this exemplary embodiment, the display area AA may include a first display area AA1 and a second display area AA2 having different resolutions, but is not limited thereto.

[0063] In this regard, for example, the first display area AA1 is an area defined in a central portion or substantially a central portion of the display area AA, and may have a relatively high first resolution. The second display area AA2 is an area defined in an outer portion of the display area AA, and may have a relatively low second resolution. As an example, the second display area AA2 having a second resolution lower than the first resolution may be defined as being positioned along the periphery of the first display area AA1 and partially or completely surrounding the first display area AA1.

[0064] Therefore, in this exemplary embodiment, the high-resolution first display area AA1 may be placed in the central portion or substantially the central portion of the display area AA, and the low-resolution second display area AA2 may be placed on the outer portion of the display area AA. As an example, the central portion may occupy half or more than half of the area of ​​the display area AA, but is not limited thereto. As an example, the boundary between the first display area AA1 and the second display area AA2 may be closer to the center of the display area AA than to the perimeter of the display area AA, or may be closer to the perimeter of the display area AA than to the center of the display area AA, but is not limited thereto. As an example, the boundary between the first display area AA1 and the second display area AA2 may have a circular shape, an arc shape, or a rectangular shape, but is not limited thereto.

[0065] In this case, the user can view a more natural image. In this regard, when the light-emitting display device 10 is used as a display device for an electronic device such as a VR, AR, or MR type device, the first display area AA1 can be located within the user's main field of view and can be set within the focus area of ​​the electronic device. Therefore, when the user views the high-resolution image portion displayed in the first display area AA1 in the main field of view, the low-resolution image portion displayed in the second display area AA2 can be viewed in the peripheral field of view outside the main field of view. Therefore, the user can view a natural image, thereby enhancing the sense of immersion in the image.

[0066] For example, in the high-resolution first display area AA1, the sub-pixels SP may be arranged in a stripe manner, but not limited thereto. In this regard, as an example, the sub-pixels SP of the same color may be arranged continuously along each column line, and the sub-pixels SP of different colors constituting the unit pixel may be arranged alternately along the row direction, but not limited thereto.

[0067] In this regard, refer to Figure 1 and Figure 3For example, the red (R) sub-pixels SPr, the green (G) sub-pixels SPg, and the blue (B) sub-pixels SPb may be arranged alternately and repeatedly along each row line. In addition, the red (R) sub-pixels SPr may be arranged continuously along the corresponding column lines (e.g., the first column line), the green (G) sub-pixels SPg may be arranged continuously along the corresponding column lines (e.g., the second column line), and the blue (B) sub-pixels SPb may be arranged continuously along the corresponding column lines (e.g., the third column line).

[0068] Therefore, in the first display area AA1, sub-pixels (SP) of the same color may be arranged continuously in each column line, and sub-pixels SPr, SPg, SPb of different colors may be arranged alternately and repeatedly in the horizontal direction. In this case, the red (R) sub-pixel SPr, the green (G) sub-pixel SPg, and the blue (B) sub-pixel SPb adjacent to each other on each row line may constitute a unit pixel.

[0069] Meanwhile, for the convenience of description, the sub-pixel SP disposed in the first display area AA1 may be referred to as a first sub-pixel SP1.

[0070] For example, in the low-resolution second display area AA2, the sub-pixels SP may be arranged in a delta manner. In this regard, the sub-pixels SP of different colors constituting the unit pixel may be arranged in a delta shape on a plane, but are not limited thereto. For example, these sub-pixels SP of a pixel may form a delta (e.g., triangle) shape.

[0071] In this regard, refer to Figure 1 and Figure 3 For example, red (R) sub-pixels SPr, green (G) sub-pixels SPg, and blue (B) sub-pixels SPb may be alternately and repeatedly arranged along each row line and spaced apart by one column line (or the width of a column line), and sub-pixels SP of the same color may be arranged along each column line and spaced apart by one row line (or the length of a row line). On two adjacent row lines, red (R) sub-pixels SPr, green (G) sub-pixels SPg, and blue (B) sub-pixels SPb may be alternately arranged in a zigzag shape along the horizontal direction.

[0072] Thus, in the second display area AA2, adjacent sub-pixels SP in each row line and each column line may be substantially spaced apart from each other by the size of the sub-pixels SP. The spacing area between adjacent sub-pixels SP substantially corresponds to a non-luminescent area and may be referred to as a non-luminescent dummy sub-pixel DSP.

[0073] Since the light emitting diode OD is substantially not formed in the non-light emitting dummy sub-pixel DSP, the non-light emitting dummy sub-pixel DSP may not have a light emitting function.

[0074] In each column line of the second display area AA2 , the dummy sub-pixel DSP may be located between two adjacent sub-pixels SP of the same color, so that the sub-pixels SP and the dummy sub-pixels DSP may be alternately arranged.

[0075] Furthermore, in each row line of the second display area AA2 , the dummy sub-pixel DSP may be located between two adjacent sub-pixels SP of different colors, so that the sub-pixels SP and the dummy sub-pixels DSP may be alternately arranged.

[0076] According to the planar arrangement of the sub-pixels SP in the second display area AA2 as described above, a delta arrangement may be implemented in the second display area AA2. In this regard, each pixel may be configured with a red (R) sub-pixel SPr, a green (G) sub-pixel SPg, and a blue (B) sub-pixel SPb arranged in a delta shape, and a non-luminous dummy sub-pixel DSP may be located inside each pixel.

[0077] Meanwhile, for convenience of explanation, the sub-pixel SP disposed in the second display area AA2 may be referred to as a second sub-pixel SP2.

[0078] In this exemplary embodiment, when the second display area AA2 is implemented in a delta (e.g., a delta or triangle configuration), for portions of the second display area AA2 located above and below the first display area AA1, the second subpixel SP2 located on the same column line as the first subpixel SP1 of the first display area AA1 may be configured to display the same color as the first subpixel SP1 of the first display area AA1. As an example, the first subpixel SP1 and the second subpixel SP2 arranged in each column line spanning the first display area AA1 and the second display area AA2 may be configured to display the same color.

[0079] In this regard, for example, when the first subpixel SP1 of the first display area AA1 is a blue (B) subpixel SPb that displays blue, the second subpixel SP2 of the second display area AA2 located on the same column line may be a blue (B) subpixel SPb that displays blue. In addition, when the first subpixel SP1 of the first display area AA1 is a red (R) subpixel SPr that displays red, the second subpixel SP2 of the second display area AA2 located on the same column line may be a red (R) subpixel SPr that displays red. In addition, when the first subpixel SP1 of the first display area AA1 is a green (G) subpixel SPg that displays green, the second subpixel SP2 of the second display area AA2 located on the same column line may be a green (G) subpixel SPg that displays green.

[0080] Therefore, when sub-pixels SP of the same color are arranged along each column line in the first display area AA1 and the second display area AA2, color shift due to lateral leakage current in the vertical direction can be prevented or reduced. In this regard, for the first display area AA1 and the second display area AA2 located above and below the first display area AA1, the first sub-pixel SP1 and the second sub-pixel SP2 arranged in each column line emit the same color, so even if lateral leakage current occurs in the vertical direction between the first display area AA1 and the second display area AA2, color shift is not substantially caused.

[0081] Therefore, in this exemplary embodiment, along the boundary between the first display area AA1 and the second display area AA2 in the horizontal direction (i.e., along the boundary between the first display area AA1 and the second display area AA2 located above and below the first display area AA1), there is no need to form a lateral leakage current blocking structure such as a groove. Alternatively, a groove may be formed at the boundary between the first display area AA1 and the second display area AA2 in the horizontal direction to block the lateral leakage current in the vertical direction.

[0082] As described above, in this exemplary embodiment, the sub-pixels SP may be formed in the low-resolution second display area AA2 configured in a delta arrangement at the outer portion of the display area AA. Therefore, the color characteristics of the image may be improved.

[0083] In this regard, in the case where the entire display area AA is configured in a stripe arrangement, asymmetry in horizontal and vertical color viewing angles and asymmetry in left and right color viewing angles may occur due to the characteristics of the stripe arrangement.

[0084] On the other hand, the delta arrangement can improve the asymmetry of the color viewing angle due to its characteristics. Therefore, in this exemplary embodiment, by applying the delta arrangement at the outer portion of the display area AA, the asymmetry of the color viewing angle can be largely alleviated, thereby improving the imbalance of the viewing angle.

[0085] Meanwhile, in this exemplary embodiment, the color filter pattern CF corresponding to the sub-pixel SP of the display area AA may be disposed on the light output surface side, for example, above the light emitting diode OD.

[0086] Here, in the first display area AA1, the color filter pattern CF (or the first color filter pattern CF1) may be formed in a stripe manner corresponding to the corresponding sub-pixel SP. Also, in the second display area AA2, the color filter pattern CF (or the second color filter pattern CF2) may be formed in a delta manner corresponding to the corresponding sub-pixel SP.

[0087] In this regard, refer to Figures 1 to 4 In the first display area AA1, corresponding to the column line of each of the red (R) sub-pixel SPr, the green (G) sub-pixel SPg and the blue (B) sub-pixel SPb, the red (R) color filter pattern CFr, the green (G) color filter pattern CFg and the blue (B) color filter pattern CFb may be provided in the form of continuously extended strips.

[0088] In this regard, the red (R) color filter pattern CFr may be formed to extend continuously along the column line continuously arranged along the red (R) sub-pixels SPr. In addition, the green (G) color filter pattern CFg may be formed to extend continuously along the column line continuously arranged along the green (G) sub-pixels SPg. In addition, the blue (B) color filter pattern CFb may be formed to extend continuously along the column line continuously arranged along the blue (B) sub-pixels SPb. The embodiment is not limited thereto. As an example, at least one or each of the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb may be separately provided for each sub-pixel arranged in the same column.

[0089] At the same time, in the second display area AA2, corresponding to each of the red (R) sub-pixel SPr, green (G) sub-pixel SPg and blue (B) sub-pixel SPb arranged in a delta shape, each of the red (R) color filter pattern CFr, green (G) color filter pattern CFg and blue (B) color filter pattern CFb can be formed.

[0090] In this regard, each of the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb may extend to both sides (i.e., left and right) in the horizontal direction, and may partially overlap with the dummy sub-pixel DSP located on the adjacent column line. As an example, each of the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb may extend to both sides (i.e., left and right) in the horizontal direction by a length equal to or less than half of the width of each sub-pixel, but is not limited thereto. As an example, each of the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb may overlap with half or less than half of the dummy sub-pixel DSP located in the adjacent column line, but is not limited thereto.

[0091] In this regard, for example, the red (R) color filter pattern CFr corresponding to the red (R) sub-pixel SPr may extend to overlap with the dummy sub-pixel DSP located on the left column line thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right column line thereof. In addition, the green (G) color filter pattern CFg corresponding to the green (G) sub-pixel SPg may extend to overlap with the dummy sub-pixel DSP located on the left column line thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right column line thereof. In addition, the blue (B) color filter pattern CFb corresponding to the blue (B) sub-pixel SPb may extend to overlap with the dummy sub-pixel DSP located on the left column line thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right column line thereof.

[0092] As an example, for a column line in which sub-pixels SPr of the same color (e.g., red (R)) are arranged, in a dummy sub-pixel DSP provided in the column line, color filter patterns CFg and CFb of two different colors (e.g., green (G) and blue (B)) located on both sides of the column line may be extended and arranged. Here, as an example, two different color filter patterns CF having portions extending into the dummy sub-pixel DSP may have substantially the same overlapping area with the dummy sub-pixel DSP (or may have substantially the same area located within the dummy sub-pixel DSP), but are not limited thereto. As an example, one of the two different color filter patterns CF having portions extending into the dummy sub-pixel DSP may have a larger overlapping area with the dummy sub-pixel DSP than the other of the two different color filter patterns CF, but are not limited thereto.

[0093] Therefore, when the color filter patterns CF of different colors are configured to extend into the dummy sub-pixel DSP, an unexpected (or abnormal) light emission phenomenon caused by a lateral leakage current in a vertical direction in the dummy sub-pixel DSP may be prevented or reduced.

[0094] In this regard, a case where a lateral leakage current flows from a blue (B) sub-pixel SPb located at the upper boundary of the first display area AA1 to a dummy sub-pixel DSP located on the upper side thereof along the light emitting layer 145 is given as an example. In this case, the red (R) color filter pattern CFr and the green (G) color filter pattern CFg on both sides of the dummy sub-pixel DSP may be extended and arranged in the dummy sub-pixel DSP. Therefore, even if a lateral leakage current flows vertically from the blue (B) sub-pixel SPb to the dummy sub-pixel DSP, the dummy sub-pixel DSP is covered by the red (R) color filter pattern CFr and the green (G) color filter pattern CFg, and blue light may be substantially reduced or prevented from being output through the dummy sub-pixel DSP.

[0095] Therefore, in this exemplary embodiment, unintended light emission in the second display area AA2 due to vertical lateral leakage current from the first display area AA1 to the second display area AA2 can be prevented or reduced. Therefore, color characteristic degradation due to lateral leakage current can be prevented or reduced.

[0096] Meanwhile, in this exemplary embodiment, Figure 3 As shown, as an example, a trench (or a first trench or a vertical trench) TC1 extending in a vertical direction along a boundary of each column line (or a boundary between two adjacent column lines) of the display area AA may be formed, but is not limited thereto.

[0097] As an example, the groove TC1 may be formed not only along the boundary of the column line passing through the first display area AA1 and the second display area AA2, but also along the boundary of the column line passing through the second display area AA2 located to the left and right of the first display area AA1. The embodiment is not limited thereto. As an example, the groove TC1 may be formed only in the first display area AA1. As an example, the groove TC1 may be formed only along the boundary of the column line passing through both the first display area AA1 and the second display area AA2, but is not limited thereto. As an example, depending on the design, the groove TC1 may be omitted.

[0098] In this way, by forming the trench TC1 along the boundary of each column line in the display area AA, it is possible to prevent or reduce the lateral leakage current from flowing in the horizontal direction between adjacent column lines where sub-pixels SP of different colors are located.

[0099] Therefore, it is possible to prevent or reduce color shift in adjacent sub-pixels SP of different colors due to lateral leakage current in the horizontal direction.

[0100] In the following, reference is made to Figures 5 to 7 Together with Figures 1 to 4 , a cross-sectional structure of the light-emitting display device 10 according to this exemplary embodiment is described in more detail. Figure 5 Schematically shows the cross-sectional structure of the sub-pixels SP arranged along the horizontal direction in the first display area AA1, Figure 6 Schematically shows the cross-sectional structure of the sub-pixels SP and the dummy sub-pixels DSP arranged in the horizontal direction in the second display area AA2, Figure 7 The cross-sectional structure of the sub-pixels SP and the dummy sub-pixels DSP arranged along the vertical direction in the second display area AA2 is schematically shown.

[0101] The substrate 101 of the light-emitting display device 10 can use, for example, an insulating substrate such as a glass substrate or a plastic substrate. As another example, the substrate 101 can use a silicon substrate (or a silicon wafer) formed of single crystal silicon used as a semiconductor, and in this case, there is an advantage of effectively realizing a small display device requiring high resolution. The embodiment is not limited to this. As an example, the substrate 101 can be a rigid substrate or a flexible substrate. As an example, the substrate 101 can include polyethylene terephthalate (PET), polycarbonate (PC), polyether sulfone (PES), polyimide (PI), etc. As an example, the substrate 101 can be a single layer or a multilayer of the same material or different materials.

[0102] In this exemplary embodiment, for convenience of explanation, a case where an insulating substrate is used is taken as an example.

[0103] A plurality of thin film transistors TR may be formed in each sub-pixel SP on the substrate 101. Meanwhile, in this exemplary embodiment, for ease of description, Figure 5 One thin film transistor TR connected to the light emitting diode OD in the red (R) sub-pixel SPr is shown. Meanwhile, the thin film transistor TR may be a light emission control thin film transistor or a driving thin film transistor, but is not limited thereto.

[0104] Meanwhile, the thin film transistor TR may include a semiconductor layer, a gate insulating layer, a gate electrode, a source electrode, and a drain electrode. As the thin film transistor TR, a thin film transistor having a so-called bottom gate structure in which the gate electrode is located below the semiconductor layer, or a thin film transistor having a so-called top gate structure in which the gate electrode is located on the semiconductor layer may be used.

[0105] Meanwhile, when a semiconductor substrate is used as the substrate 101 , an active region serving as a semiconductor layer may be formed inside the semiconductor substrate, but is not limited thereto.

[0106] At least one insulating layer may be formed on the thin film transistor TR. In this exemplary embodiment, for convenience of description, a case where three insulating layers of the first insulating layer 111 to the third insulating layer 113 are formed is taken as an example.

[0107] The first insulating layer 111 may be formed substantially over the entire surface of the substrate 101 while covering the thin film transistor TR. The first insulating layer 111 may be formed of an organic insulating material or an inorganic insulating material.

[0108] A first reflective plate 121 may be formed in the red (R) sub-pixel SPr of the display area AA (ie, the first display area AA1 and the second display area AA2) on the first insulating layer 111. As an example, the first reflective plate 121 may be omitted according to design.

[0109] The second insulating layer 112 may be formed substantially over the entire surface of the substrate 101 and on the first insulating layer 111 on which the first reflective plate 121 is formed. The second insulating layer 112 may be formed of an organic insulating material or an inorganic insulating material.

[0110] A second reflective plate 122 may be formed in the green (G) sub-pixel SPg of the display area AA (ie, the first display area AA1 and the second display area AA2) on the second insulating layer 112. As an example, the second reflective plate 122 may be omitted according to design.

[0111] The third insulating layer 113 may be formed substantially over the entire surface of the substrate 101 and on the second insulating layer 112 on which the second reflective plate 122 is formed. The third insulating layer 113 may be formed of an organic insulating material or an inorganic insulating material.

[0112] A third reflective plate 123 may be formed in the blue (B) sub-pixel SPb of the display area AA (ie, the first display area AA1 and the second display area AA2) on the third insulating layer 113. As an example, the third reflective plate 123 may be omitted according to design.

[0113] Each of the first to third reflective plates 121 to 123 may be formed of a material (e.g., metal) having a reflective property, such as Ag, Al, Mo, Ti, or APC (Al-Pd-Cu) alloy, but is not limited thereto. As an example, the first to third reflective plates 121 to 123 may be formed of the same material. As an example, at least one of the first to third reflective plates 121 to 123 may be formed of a material different from other reflective plates in the first to third reflective plates 121 to 123. As an example, the first to third reflective plates 121 to 123 may be formed on the same layer (e.g., the first insulating layer 111 or the third insulating layer 113), or may be formed on different layers. As an example, at least one of the first to third reflective plates 121 to 123 may be omitted according to design.

[0114] Meanwhile, a contact hole CH exposing one electrode (eg, a drain electrode) of the thin film transistor TR may be formed in the first to third insulating layers 111 to 113 .

[0115] The first to third reflective plates 121 to 123 may each serve to reflect, in an upward direction, light generated from the light emitting diode OD located thereon and traveling downward in the sub-pixel SP thereof.

[0116] On the substrate 101 formed with the third reflective plate 123, a first electrode (or anode) 140 of the light emitting diode OD may be formed for each sub-pixel SP. The first electrode 140 may be formed in a patterned form for each sub-pixel SP.

[0117] The first electrode 140 may be formed of a transparent conductive material such as ITO, IZO, ITZO, etc., but is not limited thereto. As an example, the first electrode 140 may also be formed of an opaque material.

[0118] The first electrode 140 formed in the red (R) subpixel SPr and the green (G) subpixel SPg may be formed on the third insulating layer 113. Also, the first electrode 140 formed in the blue (B) subpixel SPb may be formed on the third reflective plate 123 of the blue (B) subpixel SPb.

[0119] As another example, an insulating layer may be formed on the third reflective plate 123 and substantially over the entire surface of the substrate 101 , and the first electrode 140 may be formed for each sub-pixel SP on the insulating layer.

[0120] The first electrode 140 formed in each sub-pixel SP may be connected to the drain electrode of the thin film transistor TR of the corresponding sub-pixel SP through the contact hole CH.

[0121] Meanwhile, as an example, the reflective plates 121, 122, 123 and the first electrode 140 may not be formed in the dummy sub-pixel DSP as a non-luminous area in the second display area AA2. Therefore, since the reflective plates 121, 122, 123 and the first electrode 140 are not formed in the dummy sub-pixel DSP, the dummy sub-pixel DSP is not equipped with a light-emitting element and can be substantially used as a non-luminous area. Therefore, the light-emitting action of the dummy sub-pixel DSP is reduced or prevented, thereby reducing or preventing the deterioration of the color characteristics in the area. The embodiment is not limited to this. As an example, a reflective plate may also be formed in at least one of the dummy sub-pixels DSP, but is not limited thereto.

[0122] A bank (or partition) 143 surrounding the sub-pixel SP may be formed on the first electrode 140 along the edge of each sub-pixel SP. The bank 143 may be formed of an inorganic insulating material or an organic insulating material.

[0123] The bank 143 may be configured to have an opening that exposes the first electrode 140 of each sub-pixel SP and to cover the edge of the first electrode 140. Through the opening of the bank 143, a light emitting region (or light emitting diode OD) in which light is substantially generated within the sub-pixel SP may be defined. The embodiment is not limited thereto. As an example, the bank 143 may be configured not to cover the edge of the first electrode 140 and may be in contact with the edge of the first electrode 140, but is not limited thereto.

[0124] Meanwhile, as an example, similar to the sub-pixel SP, the bank 143 may be formed to surround each dummy sub-pixel DSP along the edge of each dummy sub-pixel DSP. In addition, the bank 143 may have an opening in the central region of each dummy sub-pixel DSP to expose the third insulating layer 113. The embodiment is not limited thereto. As an example, the bank 143 may not be formed in each dummy sub-pixel DSP.

[0125] Meanwhile, in the light emitting display device 10 of this exemplary embodiment, the trench TC1 may be formed in the bank 143. As described above, the trench TC1 may be formed to extend along a vertical boundary between adjacent column lines within the display area AA.

[0126] Therefore, in the first display area AA1 , the sub-pixels SP arranged in adjacent column lines may be physically divided.

[0127] Furthermore, in the second display area AA2 , the sub-pixels SP and the dummy sub-pixels DSP arranged in adjacent column lines may be physically divided.

[0128] Meanwhile, as an example, the trench TC1 may extend into the insulating layer below the bank 143. For example, the trench TC1 may be formed in at least one insulating layer including the third insulating layer 113 among the first insulating layer 111 to the third insulating layer 113. In this exemplary embodiment, the case where the trench TC1 is formed in the first insulating layer 111 to the third insulating layer 113 is taken as an example. However, the embodiment is not limited thereto. As an example, the trench TC1 may penetrate all of the first insulating layer 111 to the third insulating layer 113. As an example, the trench TC1 may penetrate into the substrate 101. As an example, the trench TC1 may penetrate into the third insulating layer 113 without penetrating the second insulating layer 112 and the third insulating layer 113.

[0129] The light emitting layer 145 may be formed on the bank 143 and the first electrode 140 exposed through the opening of the bank 143. The light emitting layer 145 may be formed substantially over the entire surface of the substrate 101 (or the entire display area AA).

[0130] For example, the light emitting layer 145 may be an organic light emitting layer formed using an organic material. In addition, the light emitting layer 145 may be formed in a single layer structure or a multi-layer structure including a light emitting material layer that actually emits light.

[0131] The light emitting layer 145 (or at least a portion of the light emitting layer 145 ) may be separated (or disconnected or divided) into each column line by a trench TC1 formed along a boundary of each column line and may have a pattern form corresponding to each column line (or may have a stripe pattern form).

[0132] Here, the light emitting layer 145 may have a single stack structure or a multi-stack structure. When the light emitting layer 145 has a single stack structure, the light emitting layer 145 may be completely separated into each column line by the groove TC1. When the light emitting layer 145 has a multi-stack structure, for example, a double-stack structure including a first stack as a lower stack, a second stack as an upper stack, and a charge generation layer between the first stack and the second stack, the first stack and the charge generation layer between the first stack and the second stack may be completely separated by the groove TC1, and at least the lower portion of the second stack may be separated. The embodiment is not limited thereto. As an example, the first stack, the charge generation layer, and the second stack may all be completely separated by the groove TC1, but is not limited thereto.

[0133] To form the light emitting layer 145 as described above, the material for the light emitting layer 145 may be deposited substantially over the entire display area AA of the substrate 101 through a deposition process. In this case, the material for the light emitting layer 145 may not be deposited on the trench TC1 but may be deposited in a form covering the inner surface of the trench TC1.

[0134] Therefore, the material for the light emitting layer 145 may have a disconnected form at the trench TC1, so that the light emitting layer 145 may be separated and formed as a pattern in each column line using the trench TC1 as a boundary, and the light emitting layer 145 may be formed to extend continuously along the entirety of each column line. The material for the light emitting layer 145 may remain on the bottom of the trench TC1 in the form of a deposit.

[0135] The light emitting layer 145 may be formed of, for example, a white light emitting layer that emits white light. Therefore, the light emitting diodes OD of all sub-pixels (SP) may emit the same white light.

[0136] As described above, in this exemplary embodiment, the trench TC1 is formed along the boundary of the column line, and the light emitting layer 145 can be physically separated from each other between adjacent column lines. Therefore, lateral leakage current in the horizontal direction through the light emitting layer 145 between adjacent column lines can be prevented or reduced.

[0137] The second electrode (or cathode) 150 may be formed on the light emitting layer 145 over substantially the entire surface of the substrate 101 .

[0138] In this regard, although there is a trench TC1 at the boundary between the column lines, the separation distance between the light emitting layers 145 at the trench TC1 may be substantially narrower than the width of the trench TC1. Therefore, the second electrode 150 may be continuously formed without being disconnected above the trench TC1, and thus, the second electrode 150 may be continuously formed along all sub-pixels SP in the display area AA.

[0139] The second electrode 150 may be formed of a material (eg, metal) having a transflective property, such as Mg, Ag, or an alloy of Mg and Ag (Mg:Ag).

[0140] As such, the reflective plate 121, 122, or 123 and the second electrode 150 are positioned at the lower and upper portions in each sub-pixel SP with the light emitting layer 145 therebetween, so that a microcavity structure may be implemented.

[0141] In this regard, the red (R) subpixel SPr, the green (G) subpixel SPg, and the blue (B) subpixel SPb output light of different colors (i.e., different wavelengths) and therefore can have different cavity thicknesses (or resonance distances) (i.e., different distances between the respective reflective plates and the second electrode).

[0142] In this regard, the sub-pixels SPr, SPg and SPb displaying red (R), green (G) and blue (B) have cavity thicknesses proportional to the wavelengths (or half-wavelengths) of the corresponding colors, and the cavity thickness of each sub-pixel SP can be matched to an integer multiple of the half-wavelength of the corresponding color.

[0143] In this regard, the sub-pixel SPr of red (R) as the longest wavelength may have a corresponding first cavity thickness by placing the first reflective plate 121 closest to the substrate. The sub-pixel SPg of green (G) as the intermediate wavelength may have a corresponding second cavity thickness by placing the second reflective plate 122 at a position higher than the first reflective plate 121. The sub-pixel SPb of blue (B) as the shortest wavelength may have a corresponding third cavity thickness by placing the third reflective plate 123 at the highest position.

[0144] Therefore, by utilizing the microcavity structure, the color purity and light efficiency can be improved.

[0145] In addition, for sub-pixels SP of different colors, corresponding microcavity thicknesses can be achieved by differentiating the positions of corresponding reflective plates 121, 122, 123. Therefore, the light emitting diodes OD of the sub-pixels SP can have substantially the same thickness, so that the light emitting diodes OD can have substantially the same characteristics.

[0146] On the second electrode 150, an encapsulation layer 160 encapsulating the substrate 101 on which the second electrode 150 is formed may be formed over the entire surface of the substrate 101. The encapsulation layer 160 may block penetration of moisture or oxygen from the outside and improve reliability.

[0147] In addition, the encapsulation layer 160 may planarize the substrate 101 on which the second electrode 150 is formed.

[0148] The encapsulation layer 160 may be formed in a single-layer structure or a multi-layer structure using at least one of an inorganic insulating material and an organic insulating material.

[0149] On the encapsulation layer 160 , a color filter pattern CF may be disposed to correspond to each sub-pixel SP and realize a corresponding color.

[0150] In this regard, the color filter pattern CF may include a red (R) filter pattern CFr, a green (G) filter pattern CFg, and a blue (B) filter pattern CFb corresponding to the red (R) sub-pixel SPr, the green (G) sub-pixel SPg, and the blue (B) sub-pixel SPb to generate red (R), green (G), and blue (B), respectively.

[0151] Therefore, the red (R) sub-pixel SPr, the green (G) sub-pixel SPg, and the blue (B) sub-pixel SPb may display corresponding colors with higher purity.

[0152] Meanwhile, as described above, in the second display area AA2, the color filter patterns CF of different colors located on both sides of the dummy sub-pixel DSP in the horizontal direction may extend to the inside of the dummy sub-pixel DSP. As an example, in the second display area AA2, the color filter patterns CF of the sub-pixels SP of each column line may extend to the inside of the dummy sub-pixels DSP located on both sides in the horizontal direction.

[0153] An overcoat film 170 may be formed on the color filter pattern CF to cover and protect the color filter pattern CF. The substrate 101 on which the overcoat film 170 is formed may have a substantially flat surface.

[0154] On the overcoat film 170 , as an example, a lens Lc corresponding to each sub-pixel SP of the display area AA may be formed. The lens Lc may have an upwardly convex shape.

[0155] The lens Lc may be substantially properly aligned with the light emitting diode OD (or light emitting area) of the corresponding sub-pixel SP. For example, the center of the lens Lc may be aligned to substantially coincide with the center of the light emitting diode OD of the sub-pixel SP.

[0156] The lens Lc can be used to collect light due to its convex shape, thereby improving the front brightness of the light-emitting display device 10.

[0157] Meanwhile, the lens Lc may not be formed in the dummy sub-pixel DSP which is a non-light emitting area in the second display area AA2.

[0158] A planarization film 180 for planarizing the substrate may be formed on the lens Lc and the overcoat film 170 .

[0159] The planarization film 180 may have a smaller refractive index than the lens Lc thereunder. In this regard, for example, the lens Lc may have a refractive index of about 1.6 to 1.8, and the planarization film 180 may have a refractive index of about 1.4 to 1.5. The embodiment is not limited thereto. As an example, as long as the planarization film 180 may have a smaller refractive index than the lens Lc thereunder, the lens Lc and the planarization film 180 may have any refractive index (for example, a refractive index lower than 1.6 or 1.4 or a refractive index higher than 1.8 or 1.5).

[0160] <Second Exemplary Embodiment>

[0161] Figure 8 and Fig. 9 are plan views schematically showing an arrangement of sub-pixels and an arrangement of color filter patterns of a light emitting display device according to a second exemplary embodiment of the present invention, respectively. Fig.10 Is magnification Fig. 9 View of area B.

[0162] In the following description, a detailed description of a configuration that is the same as or similar to that of the above-described first exemplary embodiment may be omitted or briefly given.

[0163] Reference Figures 8 to 10 In the light emitting display device 10 of this exemplary embodiment, the arrangement of the sub-pixels SP in the first display area AA1 and the second display area AA2 may be similar to that of the first exemplary embodiment.

[0164] In this regard, the first subpixel SP1 as the subpixel SP in the high-resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second subpixel SP2 as the subpixel SP in the low-resolution second display area AA2 may be configured in a delta type arrangement.

[0165] Furthermore, the arrangement of the color filter patterns CF in the first display area AA1 and the second display area AA2 may be similar to that in the first exemplary embodiment.

[0166] In this regard, the first color filter pattern CF1 as the color filter pattern CF in the high resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second color filter pattern CF2 as the color filter pattern CF in the low resolution second display area AA2 may be configured in a delta type arrangement.

[0167] Meanwhile, in this exemplary embodiment, similar to the first exemplary embodiment, the color filter pattern CF in the second display area AA2 may extend in the horizontal direction and overlap with the dummy sub-pixel DSP of the adjacent column line. In addition, the color filter pattern CF in the second display area AA2 may extend in the vertical direction and overlap with the dummy sub-pixel DSP of the adjacent row line.

[0168] In other words, as an example, for each dummy sub-pixel DSP, the color filter pattern CF of the sub-pixel SP adjacent to the dummy sub-pixel DSP in the horizontal direction may extend and overlap with the dummy sub-pixel DSP, and the color filter pattern CF of the sub-pixel SP adjacent to the dummy sub-pixel DSP in the vertical direction may extend and overlap with the dummy sub-pixel DSP.

[0169] Therefore, in this exemplary embodiment, in the second display area AA2 , the color filter pattern CF may be formed to extend from the corresponding sub-pixel SP to the dummy sub-pixel DSP in the horizontal direction and to the dummy sub-pixel DSP in the vertical direction.

[0170] Accordingly, in the second display area AA2, as an example, the color filter pattern CF may have, for example, a substantially hexagonal shape in a plan view. Embodiments are not limited thereto. As an example, the color filter pattern CF extending from the corresponding sub-pixel SP in the horizontal direction to the dummy sub-pixel DSP and the color filter pattern CF extending from the corresponding sub-pixel SP in the vertical direction to the dummy sub-pixel DSP may contact each other, but are not limited thereto. As an example, the boundaries between the color filter patterns CF within one dummy sub-pixel DSP may extend in various directions (e.g., an oblique direction other than the horizontal direction or the vertical direction) to intersect each other, but are not limited thereto.

[0171] In this regard, taking the blue (B) color filter pattern CFb as an example, the blue (B) color filter pattern CFb may have a portion extending to each of the dummy sub-pixels (DSP) located on both sides (i.e., left and right) in the horizontal direction in a substantially trapezoidal shape, and may have a portion extending to each of the dummy sub-pixels (DSP) located on both sides (i.e., upper and lower sides) in a substantially triangular shape. Therefore, the blue (B) color filter pattern CFb may be formed in a substantially hexagonal shape.

[0172] Similarly, each of the red (R) color filter pattern CFr and the green (G) color filter pattern CFg may also extend in the horizontal and vertical directions to be formed in a substantially hexagonal shape.

[0173] As such, the color filter pattern CF may be formed to extend in the horizontal and vertical directions in the second display area AA2 , so that color characteristics may become more uniform.

[0174] Meanwhile, in this exemplary embodiment, similarly to the first exemplary embodiment, a groove is formed in the vertical direction along the boundary of each column line of the display area AA. Fig.11 and Fig.12 Therefore, it is possible to prevent the lateral leakage current from flowing in the horizontal direction between adjacent column lines where sub-pixels SP of different colors are arranged.

[0175] In addition, in the exemplary embodiment, in the second display area AA2, as an example, the second lens ( Fig.11 and Fig.12 The Lc2 in the display area AA may be configured to be offset by a certain distance in the direction toward the first display area AA1. Therefore, the light generated in the second display area AA2 as a low-resolution area located in the outer part of the display area AA may be changed in path and collected to the central area as the user's main field of view, thereby improving the brightness of the outer part of the display area AA. The embodiment is not limited thereto. As an example, the second lens ( Fig.11 and Fig.12 The center of Lc2) in FIG. 1 may be configured to be aligned with the center of the light emitting diode OD of the corresponding sub-pixel SP, but is not limited thereto.

[0176] Reference Fig.11 and Fig.12 The lens shift structure of the second display area AA2 is described.

[0177] Fig.11 is a cross-sectional view schematically showing a cross-sectional structure of sub-pixels arranged in a horizontal direction in a first display area AA1 of a light-emitting display device according to a second exemplary embodiment of the present invention, Fig.12 2 is a cross-sectional view schematically showing a cross-sectional structure of sub-pixels arranged in a horizontal direction in a second display area AA2 of a light-emitting display device according to a second exemplary embodiment of the present invention.

[0178] Reference Fig.11, similar to the first exemplary embodiment, in the first display area AA1, the first lens Lc1 as the lens Lc disposed corresponding to the first subpixel SP1 may be substantially correctly aligned with the light emitting diode OD of the first subpixel SP1. For example, the center of the first lens Lc1 may be aligned to substantially coincide with the center of the light emitting diode OD of the first subpixel SP1.

[0179] At the same time, refer to Fig.12 , unlike the first exemplary embodiment, in the second display area AA2, the second lens Lc2, which is the lens Lc disposed corresponding to the second sub-pixel SP2, may be substantially misaligned with the light emitting diode OD of the second sub-pixel SP2. For example, the center of the second lens Lc2 may be offset in a direction toward the first display area AA1, and may be positioned not to coincide with the center of the light emitting diode OD of the second sub-pixel SP2. As an example, at least a portion of the second lens Lc2 may still overlap with at least a portion of the light emitting diode OD of the second sub-pixel SP2.

[0180] here, Fig.12 The second display area AA2 in the first display area AA1 is located on the right side of the first display area AA1, so that the second lens Lc2 can be offset to the left toward the first display area AA1. On this basis, the second lens Lc2 in the second display area AA2 located on the left side of the first display area AA1 can be offset to the right, the second lens Lc2 in the second display area AA2 located on the upper side of the first display area AA1 can be offset in the downward direction, and the second lens Lc2 in the second display area AA2 located on the lower side of the first display area AA1 can be offset in the upward direction. The embodiment is not limited to this. As an example, at least one of the second lenses Lc2 in the second display area AA2 located on the right side, left side, upper side and lower side of the first display area AA1 can be offset in the direction toward the first display area AA1. As an example, at least one of the second lenses Lc2 in the second display area AA2 located on the right side, left side, upper side and lower side of the first display area AA1 may not be offset in the direction toward the first display area AA1.

[0181] Therefore, in this exemplary embodiment, the second lens Lc2 may be offset toward the first display area AA1 so that the second lens Lc2 may partially overlap with the dummy sub-pixel DSP adjacent to the second lens Lc2 in the direction toward the first display area AA1. The embodiment is not limited thereto. As an example, although offset toward the first display area, the second lens Lc2 may not overlap with the dummy sub-pixel DSP adjacent to the second lens Lc2 in the direction toward the first display area AA1.

[0182] Meanwhile, the second lens Lc2 of this exemplary embodiment may be applied to the above-described first exemplary embodiment. That is, in the light-emitting display device 10 of the first exemplary embodiment, the lens Lc disposed in the second display area AA2 may be formed to be offset in a direction toward the first display area AA1.

[0183] <Third Exemplary Embodiment>

[0184] Fig.13 is a plan view schematically showing an arrangement of sub-pixels of a light-emitting display device according to a third exemplary embodiment of the present invention, Fig.14 is a plan view schematically showing an arrangement of a color filter pattern and a black matrix of a light emitting display device according to a third exemplary embodiment of the present invention. Fig.15 Is magnification Fig.14 View of area C. Fig.16 is a cross-sectional view schematically showing a cross-sectional structure of sub-pixels arranged in a horizontal direction in a second display area of ​​a light-emitting display device according to a third exemplary embodiment of the present invention.

[0185] In the following description, a detailed description of configurations that are the same as or similar to those of the above-described first and second exemplary embodiments may be omitted or briefly given.

[0186] Reference Figures 13 to 16 In the light emitting display device 10 of this exemplary embodiment, the arrangement of the sub-pixels SP in the first display area AA1 and the second display area AA2 may be similar to that in the first exemplary embodiment.

[0187] In this regard, the first subpixel SP1 as the subpixel SP in the high-resolution first display area AA1 may be configured in a stripe arrangement. Also, the second subpixel SP2 as the subpixel SP in the low-resolution second display area AA2 may be configured in a delta array structure.

[0188] In addition, the arrangement structure of the color filter patterns CF in the first display area AA1 and the second display area AA2 may be similar to that in the first exemplary embodiment.

[0189] In this regard, the first color filter pattern CF1 as the color filter pattern CF in the high resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second color filter pattern CF2 as the color filter pattern CF in the low resolution second display area AA2 may be configured in a delta type arrangement.

[0190] Meanwhile, in this exemplary embodiment, a black matrix BM corresponding to each dummy sub-pixel DSP may be formed in the second display area AA2. As an example, the black matrix BM may be formed on the encapsulation layer 160, but is not limited thereto. As an example, the black matrix BM may be formed on the same layer or on a different layer as the color filter pattern. As an example, the edge of the black matrix BM may contact the edge of the color filter pattern. As an example, the boundary between the black matrix BM and the color filter pattern may be located between adjacent sub-pixels and the dummy sub-pixel DSP, or may be located inside the dummy sub-pixel DSP, but is not limited thereto. The black matrix BM may be formed corresponding to the dummy sub-pixel DSP so that the black matrix BM may be formed in an island pattern shape.

[0191] Therefore, since the black matrix BM is formed in the dummy subpixel DSP of the second display area AA2, the second color filter pattern CF2 as the color filter pattern CF of the second display area AA2 may be formed to have a size (or area) substantially corresponding to the second subpixel SP2.

[0192] In other words, as an example, unlike the first and second exemplary embodiments, the second color filter pattern CF2 may not extend to the dummy sub-pixel DSP adjacent thereto in the horizontal direction, and may not extend to the dummy sub-pixel DSP adjacent thereto in the vertical direction. That is, the second color filter pattern CF2 may be formed so as not to overlap the dummy sub-pixel DSP adjacent thereto in the horizontal and vertical directions.

[0193] As described above, when the black matrix BM is formed in the dummy sub-pixel DSP of the second display area AA2 , light output from the dummy sub-pixel DSP may be prevented or reduced.

[0194] Therefore, even if a lateral leakage current in the vertical direction flows into the dummy sub-pixel DSP, unintended light emission caused thereby can be prevented or reduced, and thus degradation of color characteristics due to the lateral leakage current in the vertical direction can be prevented or reduced.

[0195] Meanwhile, in this exemplary embodiment, similar to the first and second exemplary embodiments, a trench TC1 may be formed in the vertical direction along the boundary of each column line of the display area AA, so that lateral leakage current may be prevented from flowing in the horizontal direction between adjacent column lines where sub-pixels SP of different colors are arranged.

[0196] In addition, in this exemplary embodiment, similar to the second exemplary embodiment, in the second display area AA2, the second lens Lc2, which is the lens Lc disposed on the second color filter pattern CF2, may be configured to be offset by a certain distance in the direction toward the first display area AA1. Therefore, light generated in the second display area AA2, which is a low-resolution area located in the outer portion of the display area AA, may be changed in path and collected to the central area, which is the main field of view of the user, so that the brightness of the outer portion of the display area AA may be improved.

[0197] <Fourth Exemplary Embodiment>

[0198] Fig.17 and Fig.18 are plan views schematically showing an arrangement of sub-pixels and an arrangement of color filter patterns of a light emitting display device according to a fourth exemplary embodiment of the present invention, respectively. Fig.19 and Fig. 20 Amplify Fig.17 and Fig.18 View of area D. Fig.21 It is along Fig.19 A cross-sectional view taken along line XXI-XXI'.

[0199] In the following description, a detailed description of configurations that are the same as or similar to those of the above-described first to third exemplary embodiments may be omitted or briefly given.

[0200] Reference Figures 17 to 21 In the light emitting display device 10 of this exemplary embodiment, the arrangement of the sub-pixels SP in the first display area AA1 and the second display area AA2 may be similar to that in the first exemplary embodiment.

[0201] In this regard, the first subpixel SP1 as the subpixel SP in the high-resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second subpixel SP2 as the subpixel SP in the low-resolution second display area AA2 may be configured in a delta type arrangement.

[0202] Furthermore, the arrangement of the color filter patterns CF in the first display area AA1 and the second display area AA2 may be similar to that in the first exemplary embodiment.

[0203] In this regard, the first color filter pattern CF1 as the color filter pattern CF in the high resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second color filter pattern CF2 as the color filter pattern CF in the low resolution second display area AA2 may be configured in a delta type arrangement.

[0204] Meanwhile, in this exemplary embodiment, the arrangement relationship between the red (R) sub-pixel SPr, the green (G) sub-pixel SPg, and the blue (B) sub-pixel SPb of the second sub-pixel SP2 in the second display area AA2 may be different from that of the first exemplary embodiment. Therefore, the arrangement relationship between the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb of the second color filter pattern CF2 may be different from that of the first exemplary embodiment.

[0205] For example, with respect to the red (R) sub-pixels SPr, green (G) sub-pixels SPg, and blue (B) sub-pixels SPb arranged in the first to third column lines which are three adjacent column lines, on one column line among the three column lines, the first sub-pixels SP1 and the second sub-pixels SP2 of the same colors may be arranged in the first display area AA1 and the second display area AA2, and on each of the remaining two column lines among the three column lines, the first sub-pixels SP1 and the second sub-pixels SP2 of different colors may be arranged in the first display area AA1 and the second display area AA2.

[0206] In this exemplary embodiment, for ease of explanation, the following situation is used as an example, wherein, along the third column line, the blue (B) sub-pixel SPb is identically arranged in the first display area AA1 and the second display area AA2; along the first column line, the red (R) sub-pixel SPr is arranged in the first display area AA1, and the green (G) sub-pixel SPg is arranged in the second display area AA2; and along the second column line, the green (G) sub-pixel SPg is arranged in the first display area AA1, and the red (R) sub-pixel SPr is arranged in the second display area AA2.

[0207] With this arrangement relationship, the blue (B) subpixel SPb may cause the largest color shift due to its lateral leakage current. Therefore, in order to reduce or minimize the color shift, the blue (B) subpixel SPb may be positioned on the same column line of the first display area AA1 and the second display area AA2.

[0208] Alternatively, the red (R) sub-pixel SPr or the green (G) sub-pixel SPg may be configured to be arranged in the same column line of the first display area AA1 and the second display area AA2.

[0209] The arrangement relationship of the red (R) color filter pattern CFr, the green (G) color filter pattern CFg, and the blue (B) color filter pattern CFb in the first display area AA1 and the second display area AA2 can be set to correspond to the arrangement relationship of the red (R) sub-pixel SPr, the green (G) sub-pixel SPg, and the blue (B) sub-pixel SPb in the first display area and the second display area (AA1, AA2) as described above.

[0210] In this regard, along the third column line, the blue (B) color filter pattern CFb can be arranged in both the first display area AA1 and the second display area AA2; along the first column line, the red (R) color filter pattern CFr can be arranged in the first display area AA1, and the green (G) color filter pattern CFg can be arranged in the second display area AA2; and along the second column line, the green (G) color filter pattern CFg can be arranged in the first display area AA1, and the red (R) color filter pattern CFr can be arranged in the second display area AA2.

[0211] Similar to the first exemplary embodiment, the color filter pattern CF in the second display area AA2 may extend in the horizontal direction and overlap with the dummy sub-pixel DSP located in an adjacent column line thereof.

[0212] In this regard, for example, the red (R) color filter pattern CFr corresponding to the red (R) sub-pixel SPr may extend to overlap with the dummy sub-pixel DSP located on the left side thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right side thereof. In addition, the green (G) color filter pattern CFg corresponding to the green (G) sub-pixel SPg may extend to overlap with the dummy sub-pixel DSP located on the left side thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right side thereof. In addition, the blue (B) color filter pattern CFb corresponding to the blue (B) sub-pixel SPb may extend to overlap with the dummy sub-pixel DSP located on the left side thereof, and may also extend to overlap with the dummy sub-pixel DSP located on the right side thereof.

[0213] Meanwhile, in this exemplary embodiment, similarly to the first exemplary embodiment, the first trench TC1 as a trench extending in the vertical direction along the boundary of each column line of the display area AA may be formed.

[0214] In addition, in this exemplary embodiment, a second groove TC2 may be formed as a groove extending in the horizontal direction along a horizontal boundary between the first display area AA1 and the second display area AA2 (i.e., a horizontal boundary between the first display area AA1 and the second display area AA2 located above the first display area AA1, and a horizontal boundary between the first display area AA1 and the second display area AA2 located below the first display area AA1).

[0215] Here, the second groove TC2 may be formed in the column lines where the sub-pixels SP of different colors are arranged in the first display area AA1 and the second display area AA2, for example, in the first column line and the second column line where the red (R) sub-pixel SPr and the green (G) sub-pixel SPg are arranged in the first display area AA1 and the second display area AA2. In this regard, the second groove TC2 may be formed between the first sub-pixel SP1 closest to the boundary of the first display area AA1 and the second sub-pixel SP2 closest to the boundary of the second display area AA2 or the dummy sub-pixel DSP.

[0216] In addition, the second groove TC2 may not be formed in the column line in which the sub-pixels SP of the same color are arranged in the first display area AA1 and the second display area AA2, for example, not formed in the third column line in which the blue (B) sub-pixel SPb is arranged in the first display area AA1 and the second display area AA2. As another example, the second groove TC2 may be formed in the third column line in which the blue (B) sub-pixel SPb is arranged.

[0217] As described above, on the column line where the sub-pixels SP of the first display area AA1 and the sub-pixels SP of the second display area AA2 have different colors, the horizontal second groove TC2 may be formed at the horizontal boundary between the first display area AA1 and the second display area AA2, so that the lateral leakage current in the vertical direction between the first display area AA1 and the second display area AA2 may be blocked. Therefore, the occurrence of color shift due to the lateral leakage current in the vertical direction in the column line where the sub-pixels SP of different colors are arranged may be prevented or reduced.

[0218] Meanwhile, in the column lines of the same color of the sub-pixels SP of the first display area AA1 and the second display area AA2, the horizontal second groove TC2 may not be formed at the boundary between the first display area AA1 and the second display area AA2. In this regard, as mentioned earlier in the first exemplary embodiment, the lateral leakage current flows in the vertical direction in the column lines of the same color, and thus, in the sub-pixels SP located in the column lines, a color shift is not substantially caused. In addition, in the dummy sub-pixels DSP arranged in the column lines of the same color, a color filter pattern CF of a color different from the color of the column lines may be arranged, so that accidental light emission of the dummy sub-pixels DSP due to the lateral leakage current may be prevented or reduced, thereby reducing or preventing the degradation of the color characteristics.

[0219] The second trench TC2 may be formed, for example, to be spaced apart from the first trench TC1 extending in the vertical direction without intersecting (or meeting) the first trench TC1. As an example, the end of the second trench TC2 may be formed to be spaced apart from the first trench TC1 extending along the boundary of the corresponding column line. That is, the second trenches TC2 formed in two adjacent column lines may be formed to be spaced apart from each other and to have the first trench TC1 along the boundary between the two column lines located therebetween.

[0220] In this regard, if the second trench TC2 is formed to intersect and meet the first trench TC1, the trench width at and near the intersection of the first and second trenches TC1 and TC2 may increase, in which case the second electrode 150 of the light emitting diode OD may be inadvertently cut off.

[0221] Therefore, in this exemplary embodiment, the second trench TC2 may be formed to be spaced apart from the first trench TC1 without intersecting the first trench TC1 , thereby reducing or preventing defects from occurring in the light emitting diode OD.

[0222] Meanwhile, as an example, the second trench TC2 may be formed in the same process as the first trench TC1. For example, the second trench TC2 may be formed in the bank 143 and may extend into the insulating layer below the bank 143 or into the substrate 101. Embodiments are not limited thereto. As an example, the second trench TC2 and the first trench TC1 may be formed in separate processes. As an example, the second trench TC2 may have the same thickness and / or the same width as the first trench TC1, or may have a different thickness and / or a different width than the first trench TC1.

[0223] Meanwhile, in the light-emitting display device 10 of the exemplary embodiment, the lens Lc disposed in the second display area AA2 may be properly aligned with the corresponding light-emitting diode OD. As another example, similar to the above-described second exemplary embodiment, the lens Lc disposed in the second display area AA2 may be formed to be offset in a direction toward the first display area AA1.

[0224] <Fifth Exemplary Embodiment>

[0225] Fig. 22 and Fig.23 are plan views schematically showing an arrangement of sub-pixels and an arrangement of color filter patterns of a light-emitting display device according to a fifth exemplary embodiment of the present invention, respectively. Fig.24 Is magnification Fig. 22 View of area E.

[0226] In the following description, a detailed description of configurations that are the same as or similar to those of the above-described first to fourth exemplary embodiments may be omitted or briefly given.

[0227] Reference Figure 22 to Figure 24 In the light emitting display device 10 of this exemplary embodiment, the arrangement of the sub-pixels SP in the first display area AA1 and the second display area AA2 may be similar to that in the fourth exemplary embodiment.

[0228] In this regard, the first subpixel SP1 as the subpixel SP in the high-resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second subpixel SP2 as the subpixel SP in the low-resolution second display area AA2 may be configured in a delta type arrangement.

[0229] In addition, the arrangement of the color filter patterns CF in the first display area AA1 and the second display area AA2 may be similar to that in the fourth exemplary embodiment.

[0230] In this regard, the first color filter pattern CF1 as the color filter pattern CF in the high resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second color filter pattern CF2 as the color filter pattern CF in the low resolution second display area AA2 may be configured in a delta type arrangement.

[0231] Meanwhile, in this exemplary embodiment, similar to the second exemplary embodiment, the color filter pattern CF in the second display area AA2 may extend in the horizontal direction and overlap with the dummy sub-pixel DSP of the adjacent column line. In addition, the color filter pattern CF in the second display area AA2 may extend in the vertical direction and overlap with the dummy sub-pixel DSP of the adjacent row line.

[0232] As an example, for each dummy sub-pixel DSP, the color filter pattern CF of the sub-pixel SP adjacent to the dummy sub-pixel DSP in the horizontal direction may extend and overlap with the dummy sub-pixel DSP, and the color filter pattern CF of the sub-pixel SP adjacent to the dummy sub-pixel DSP in the vertical direction may extend and overlap with the dummy sub-pixel DSP.

[0233] Therefore, in this exemplary embodiment, in the second display area AA2 , the color filter pattern CF may be formed to extend from the corresponding sub-pixel SP to the dummy sub-pixel DSP in the horizontal direction and the dummy sub-pixel DSP in the vertical direction.

[0234] Accordingly, in the second display area AA2, the color filter pattern CF may have, for example, a substantially hexagonal shape in a plan view.

[0235] As such, the color filter pattern CF may be formed to extend in the horizontal and vertical directions in the second display area AA2 , so that color characteristics may become more uniform.

[0236] Meanwhile, in this exemplary embodiment, similarly to the fourth exemplary embodiment, the first trench TC1 is formed in the vertical direction along the boundary of each column line of the display area AA.

[0237] In addition, similar to the fourth exemplary embodiment, the second trench TC2 may be formed at a horizontal boundary between the first display area AA1 and the second display area AA2 .

[0238] Therefore, lateral leakage currents of different colors may be blocked from flowing in the vertical and horizontal directions, thereby reducing or preventing color shift in adjacent sub-pixels SP.

[0239] In this exemplary embodiment, similar to the second exemplary embodiment, in the second display area AA2, the second lens ( Fig.11 and Fig.12 Lc2 in the display area AA can be configured to be offset by a certain distance in the direction toward the first display area AA1. Therefore, light generated in the second display area AA2 as a low-resolution area located in the outer part of the display area AA can be changed in path and collected in the central area as the user's main field of view, so that the brightness of the outer part of the display area AA can be improved.

[0240] <Sixth Exemplary Embodiment>

[0241] Fig.25 is a plan view schematically showing an arrangement of sub-pixels of a light-emitting display device according to a sixth exemplary embodiment of the present invention, Fig.26 is a plan view schematically showing an arrangement of a color filter pattern and a black matrix of a light emitting display device according to a sixth exemplary embodiment of the present invention. Fig. 27 Is magnification Fig.25 View of area F.

[0242] In the following description, a detailed description of configurations that are the same as or similar to those of the above-described first to fifth exemplary embodiments may be omitted or briefly given.

[0243] Reference Figure 25 to Figure 27 In the light emitting display device 10 of this exemplary embodiment, the arrangement of the sub-pixels SP in the first display area AA1 and the second display area AA2 may be similar to that in the fourth exemplary embodiment or the fifth exemplary embodiment.

[0244] In this regard, the first subpixel SP1 as the subpixel SP in the high-resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second subpixel SP2 as the subpixel SP in the low-resolution second display area AA2 may be configured in a delta type arrangement.

[0245] In addition, the arrangement of the color filter patterns CF in the first display area AA1 and the second display area AA2 may be similar to that in the fourth exemplary embodiment.

[0246] In this regard, the first color filter pattern CF1 as the color filter pattern CF in the high resolution first display area AA1 may be configured in a stripe type arrangement. Also, the second color filter pattern CF2 as the color filter pattern CF in the low resolution second display area AA2 may be configured in a delta type arrangement.

[0247] Meanwhile, in this exemplary embodiment, similar to the third exemplary embodiment, a black matrix BM may be formed corresponding to each dummy sub-pixel DSP in the second display area AA2 . The black matrix BM may be formed corresponding to the dummy sub-pixel DSP so that the black matrix BM may be formed in an island pattern shape.

[0248] Therefore, since the black matrix BM is formed in the dummy sub-pixel DSP of the second display area AA2 , the second color filter pattern CF2 as the color filter pattern CF of the second display area AA2 may be formed to have a size substantially corresponding to the second sub-pixel SP2 .

[0249] As an example, the second color filter pattern CF2 may not extend to the dummy sub-pixel DSP adjacent thereto in the horizontal direction, and may not extend to the dummy sub-pixel DSP adjacent thereto in the vertical direction. That is, the second color filter pattern CF2 may be formed not to overlap the dummy sub-pixel DSP adjacent thereto in the horizontal and vertical directions.

[0250] As described above, when the black matrix BM is formed in the dummy sub-pixel DSP of the second display area AA2 , light output from the dummy sub-pixel DSP may be prevented or reduced.

[0251] Therefore, even if a lateral leakage current in the vertical direction flows into the dummy sub-pixel DSP, unintended light emission caused thereby can be prevented or reduced, and thus degradation of color characteristics due to the lateral leakage current in the vertical direction can be prevented or reduced.

[0252] Meanwhile, in this exemplary embodiment, similarly to the fourth exemplary embodiment or the fifth exemplary embodiment, the first trench TC1 is formed in the vertical direction along the boundary of each column line of the display area AA.

[0253] In addition, similar to the fourth exemplary embodiment or the fifth exemplary embodiment, the second trench TC2 may be formed at a horizontal boundary between the first display area AA1 and the second display area AA2 .

[0254] Therefore, lateral leakage currents of different colors may be blocked from flowing in the vertical and horizontal directions, thereby reducing or preventing color shift in adjacent sub-pixels SP.

[0255] In this exemplary embodiment, similar to the third exemplary embodiment, in the second display area AA2, the second lens ( Fig.16 Lc2 in the display area AA can be configured to be offset by a certain distance in the direction toward the first display area AA1. Therefore, light generated in the second display area AA2 as a low-resolution area located in the outer part of the display area AA can be changed in path and collected in the central area as the user's main field of view, so that the brightness of the outer part of the display area AA can be improved.

[0256] As described above, according to an exemplary embodiment of the present invention, a high-resolution first display area can be formed at a central portion of the display area and sub-pixels can be arranged in a strip manner, and a low-resolution second display area can be formed at an outer portion of the display area and sub-pixels can be arranged in a delta manner.

[0257] By applying a delta arrangement to the outer portion of the display area, the asymmetry of the color viewing angle can be alleviated, thereby improving the imbalance of the viewing angle. In addition, since the outer portion of the display area has a lower resolution, the user can view a natural image, thereby improving the sense of immersion in the image.

[0258] In addition, a vertical groove may be formed along the boundary of each column line in the display area, or alternatively, a horizontal groove may be formed along the horizontal boundary between the first display area and the second display area. Thus, lateral leakage current may be prevented from flowing in the vertical direction or in the vertical and horizontal directions, thereby reducing or preventing color shift in adjacent sub-pixels of different colors.

[0259] Furthermore, in the second display region, the color filter pattern may be formed to extend to adjacent dummy sub-pixels in the horizontal direction or in the horizontal and vertical directions. Therefore, the color characteristics of the light emitting display device may become more uniform.

[0260] In addition, the lens located in the second display area can be configured to be offset in a direction toward the first display area. Therefore, the light in the second display area can be collected into the user's main field of view, thereby improving the brightness of the outer part of the display area.

[0261] In addition, a black matrix may be formed in the dummy sub-pixel of the second display area. Therefore, even if lateral leakage current flows into the dummy sub-pixel, light output may be reduced or prevented, thereby reducing or preventing degradation of color characteristics due to the dummy sub-pixel.

[0262] It is obvious to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalents.
