[0038] Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings; however, example embodiments may be implemented in 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 example embodiments to those skilled in the art.

[0039] In the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity. It will also be understood that when a layer or element is referred to as being "on" another layer or substrate, the layer or element may be directly on the other layer or substrate, or there may be an intermediate layer. In addition, it will be understood that when a layer is referred to as being "below" another layer, the layer may be directly below, or there may be one or more intermediate layers. In addition, it will be understood that when a layer is referred to as being "between" two layers, the layer may be the only layer between the two layers, or there may be one or more intermediate layers. The same reference numerals represent the same elements throughout.

[0040] Throughout the specification, the word “on” related to a target element shall be understood to mean positioned above or below the target element, and does not necessarily mean to be understood as positioned “at the upper side” based only on the direction opposite to gravity.

[0041] Throughout the specification, the expression "in a plan view" means a view in which a plane parallel to two directions (e.g., the first direction DR1 and the second direction DR2) intersecting each other is observed, and the expression "in a cross-sectional view" means a view in which a plane cut in a direction perpendicular to the plane parallel to the first direction DR1 and the second direction DR2 is observed. In addition, when two constituent elements are stacked, it means that the two constituent elements are stacked in a third direction DR3 (e.g., a direction perpendicular to the top surface of the substrate) unless otherwise specified.

[0042] In the following, reference will be made to Figures 1 to 4 A structure of a display device according to an exemplary embodiment will be described. Figure 1 , Figure 2 and Figure 3 shows a schematic layout diagram of a display area of ​​a display device according to a corresponding exemplary embodiment, Figure 4 A schematic cross-sectional view of a display device according to an exemplary embodiment is shown.

[0043] Reference Figures 1 to 4 The display area included in the display devices 1000, 1000a, 1000b, and 1000c according to the corresponding exemplary embodiments is an area where an image can be displayed. Each display area may include a first display area DA1 and a second display area DA2 that can display an image and may also have other functions.

[0044] A larger amount of light having a wavelength different from that of light displaying an image may be incident into or emitted from the second display area DA2 than in the first display area DA1.

[0045] For example, refer to Figure 4 , the display device 1000 according to an exemplary embodiment may include a display panel 30 and an optical member 500 located behind the display panel 30. Light of a wavelength used by the optical member 500 may pass through the second display area DA2 with higher transmittance than the first display area DA1.

[0046] In the second display area DA2, a ratio of an area where an image may be displayed (ie, an area occupied by pixels) may be smaller than a ratio of an area occupied by pixels in the first display area DA1.

[0047] The second display area DA2 may include a pixel area and a light-transmitting area. The light transmittance of the light-transmitting area may be higher than the light transmittance of the pixel area. When there is no pixel in the light-transmitting area, the light of the desired image cannot be displayed. Here, the term "pixel" may refer to a unit area that emits light of an image.

[0048] Reference Figure 1 In a plan view, the second display area DA2 may be surrounded by the first display area DA1 and may be located at the periphery of one side of the display device 1000a. For example, in a plan view, a portion of the first display area DA1 may be disposed between the second display area DA2 and an edge of the display device 1000a. For example, the second display area DA2 may be disposed near an upper end of the display device 1000a and may be formed in the shape of a plane extending in the first direction DR1 along most of the upper edge of the display device 1000a.

[0049] Reference Figure 2 , except that the first display area DA1 may not be disposed at the periphery of at least one side of the second display area DA2, the second display area DA2 according to the present exemplary embodiment may be Figure 1 000b. For example, in a plan view, one edge of the second display area DA2 may match one edge of the display device 1000b. For example, when the second display area DA2 is located near the upper edge of the display device 1000b, the first display area DA1 may not be disposed in the upper side of the second display area DA2.

[0050] Reference Figure 3 In addition to the second display area DA2 being located adjacent to or near a corner of the display device 1000c, the second display area DA2 according to the present exemplary embodiment may be located adjacent to or near a corner of the display device 1000c. Figure 2 000c. In a plan view, one edge of the second display area DA2 may match one corner of the display device 1000c. For example, when the second display area DA2 is located near an upper corner of the display device 1000c, one edge of the second display area DA2 may match one edge of an upper corner of the first display area DA1.

[0051] In some embodiments, the second display area DA2 may be disposed in various plane shapes at various positions in the display area of ​​the display device. As an example, the second display area DA2 may have a circular plane shape located near an upper edge of the display area.

[0052] Reference Figure 4 , the display panel 30 of the display device 1000 may include the substrate 10 disposed in the first display area DA1 and the second display area DA2 described above. For example, the substrate 10 may be continuously formed in the second display area DA2, and there may be a portion that is not removed.

[0053] A plurality of pixels PX may be formed between the substrate 10 and the encapsulation substrate 20. A sealant 310 disposed between the substrate 10 and the encapsulation substrate 20 may also be positioned at an edge of the display panel 30. An optical member 500 may be disposed under the display panel 30. The optical member 500 may be, for example, a camera, a flash, a sensor, or the like.

[0054] The optical member 500 may emit light of a constant wavelength toward an object 600 located on the display panel 30, or may receive light reflected by the object 600. Such light of a constant wavelength may be processed by the optical member 500. The light may be light of a wavelength other than a visible light region, which is light of an image displayed on the pixel PX. The light of a constant wavelength may substantially pass through a light-transmitting region located in the second display area DA2. When the optical member 500 is an infrared camera, the light of a given wavelength may be, for example, infrared light of about 900nm to 1000nm.

[0055] The optical member 500 may correspond to the entire area of ​​the second display area DA2 in a plan view, or may correspond to only some areas of the second display area DA2. Figure 1 Some areas of the second display area DA2 are shown in FIG.

[0056] Will refer to Figures 5 to 20 and the above-mentioned drawings to describe the first display area DA1 and the second display area DA2 of the display device according to an exemplary embodiment.

[0057] Figures 5 to 121 is a layout diagram of a first display area DA1 and a second display area DA2 of a display device according to each of the corresponding exemplary embodiments. Figures 13 to 20 A pixel region of a display device according to each of the respective exemplary embodiments is shown.

[0058] The first display area DA1 may include a plurality of pixel areas PU1. The second display area DA2 may include a plurality of pixel areas PU2 and a light-transmitting area TA.

[0059] In the first display area DA1, the plurality of pixel areas PU1 may be arranged, for example, in a matrix form in which the first direction DR1 and the second direction DR2 or two diagonal directions intersecting each other are rows and columns. In the second display area DA2, the plurality of pixel areas PU2 and the light-transmitting area TA may be arranged, for example, in a matrix form. Here, the term "diagonal direction" refers to a direction intersecting both the first direction DR1 and the second direction DR2.

[0060] Each of the pixel areas PU1 and PU2 may include a plurality of pixels or a single pixel. The structure of the pixel area PU1 and the structure of the pixel area PU2 may be the same as or different from each other. Two adjacent pixel areas PU1 in the first display area DA1 may have the same or different structures, and two adjacent pixel areas PU2 in the second display area DA2 may have the same or different structures. For example, two pixel areas PU1 adjacent to each other in the row direction or the column direction in the first display area DA1 may have structures symmetrical to each other, and two pixel areas PU2 adjacent to each other in the row direction or the column direction in the second display area DA2 may have structures symmetrical to each other.

[0061] Figures 13 to 20 The corresponding pixel areas PU1 and PU2 are shown respectively.

[0062] Reference Figures 13 to 18 , each pixel region PU1 and / or pixel region PU2 may include a plurality of pixels that each output a different color. The plurality of pixels included in each of the pixel regions PU1 and PU2 may output three or four primary colors of red, green, and blue, or may output cyan, magenta, yellow, and / or white. For example, each pixel region PU1 and / or each pixel region PU2 may include a red pixel R, a green pixel G, and a blue pixel B.

[0063] Figures 13 to 15 as well as Fig.17 An example is shown in which each pixel region PU1 and / or each pixel region PU2 includes one red pixel R, one green pixel G, and one blue pixel B.

[0064] exist Fig.13In the exemplary embodiment shown in , the pixels R, G, and B included in one pixel area PUa may have the same shape (such as a rectangle as an example), and may be arranged in one direction.

[0065] exist Fig.14 In the exemplary embodiment shown in , the pixels R, G, and B included in one pixel area PUb may have a substantially rectangular shape, respectively. Two pixels (e.g., a red pixel R and a green pixel G) among the three pixels R, G, and B may be arranged vertically adjacent to each other, and the remaining one pixel (a blue pixel B) may be arranged in the vertical direction at one side of the red pixel R and the green pixel G. The red pixel R and the green pixel G may extend in the horizontal direction, respectively.

[0066] exist Fig.15 In the exemplary embodiment shown in , the pixels R, G, and B included in one pixel region PUc may have a substantially rhombus shape, respectively. The sizes of the red pixel R, the green pixel G, and the blue pixel B may be different from each other. For example, the blue pixel B may be the largest, and the green pixel G may be the smallest.

[0067] Fig.16 An example is shown in which the pixel area PU1 and / or the pixel area PU2 includes one red pixel R, one blue pixel B, and two green pixels G. Each of the pixels R, G, and B included in each pixel area PUd may substantially have a rhombus shape. The sizes of the red pixel R, the green pixel G, and the blue pixel B may be different from each other. For example, the blue pixel B may be the largest, and the green pixel G may be the smallest.

[0068] Fig.17 and Fig.18 In addition to the positions of the red pixel R and the blue pixel B included in one pixel area PUe and PUf, the positions of the red pixel R and the blue pixel B included in one pixel area PUe and PUf may be different from those of the exemplary embodiment of Fig.15 and Fig.16 The positions of the red pixels R and the blue pixels B in the pixel areas PUc and PUd shown in FIG. Fig.15 and Fig.16 The exemplary embodiments of are almost the same.

[0069] Reference Fig.19 and Fig. 20 Each pixel region PU1 and / or each pixel region PU2 may include only one pixel representing the same color. Fig.19 and Fig. 20It is exemplarily shown that one of the pixel areas PUg and PUh includes only red pixels R, but this is not restrictive. Each of the pixel areas PUg and PUh may include only green pixels G or only blue pixels B. In this case, the first display area DA1 and / or the second display area DA2 may display a single color among red, green, and blue.

[0070] Reference Fig.19 , the pixels R included in one pixel area PUg may be formed substantially in a rhombus shape.

[0071] Reference Fig. 20 , the pixels R included in one pixel area PUh may be formed substantially in a rectangular shape.

[0072] exist Figures 13 to 20 In the exemplary embodiment shown in FIG. 1 , various changes may be made to the order, arrangement, and number of red pixels R, green pixels G, and blue pixels B shown in the drawings. Fig.16 In the exemplary embodiment shown in , the red pixel R, the green pixel G, the blue pixel B, and the green pixel G are shown in this order, but they may be arranged in the order of the red pixel R, the blue pixel B, the green pixel G, and the blue pixel B.

[0073] Reference Figure 5 In the second display area DA2, the light-transmitting area TA may be disposed between two pixel areas PU2 adjacent to each other in the first direction DR1, the second direction DR2, and the diagonal direction. For example, the pixel areas PU2 and the light-transmitting areas TA may be alternately arranged in the first direction DR1, the second direction DR2, and the diagonal direction.

[0074] As described above, the light transmittance of the light-transmitting area TA is higher than the light transmittance of the pixel area PU2. A pixel as an image display unit that can emit light to display an image may not be formed in the light-transmitting area TA.

[0075] In the second display area DA2, the area of ​​each light-transmitting area TA between two pixel areas PU2 adjacent in the first direction DR1 and the second direction DR2 may be the same, similar, or different from the area of ​​one pixel area PU2. In some embodiments, the area of ​​the light-transmitting area TA may vary rather than be constant. One light-transmitting area TA having an area corresponding to the area of ​​one pixel area PU2 may be referred to as a "unit light-transmitting area TA".

[0076] In the display device according to an exemplary embodiment, the common electrode 270 may be located in the first display area DA1 and the second display area DA2. The common electrode 270 in the first display area DA1 and the common electrode 270 in the second display area DA2 may be connected to each other as one electrode and may transmit a constant common voltage.

[0077] The common electrode 270 in the first display area DA1 may be continuously formed as a single electrode without cutouts, openings, patterns, etc. For example, the common electrode 270 disposed in the first display area DA1 may have a substantially uniform thickness.

[0078] The common electrode 270 disposed in the second display area DA2 may have a plurality of patterned areas 275. In a plan view, the plurality of patterned areas 275 may correspond to at least a portion of the light-transmitting area TA. The common electrode 270 except the patterned area 275 may be located in the pixel area PU2. In a plan view, the patterned area 275 of the common electrode 270 may have a planar shape corresponding to almost the entire area of ​​the light-transmitting area TA.

[0079] In the patterned area 275, the common electrode 270 may be completely removed. Thus, an opening area may be formed. The common electrode 270 may be partially removed in the thickness direction in a cross-sectional view so that the thickness may be thinner than the thickness of the common electrode 270 formed in an area other than the patterned area 275. That is, the thickness of the common electrode 270 corresponding to the light-transmitting area TA may be less than the thickness of the common electrode 270 corresponding to the pixel area PU2, or the thickness of the common electrode 270 corresponding to the light-transmitting area TA may be zero.

[0080] Therefore, the transmittance in the light-transmitting area TA may be higher than the transmittance in the pixel areas PU1 and PU2. When light emitted from the optical member 500 disposed behind the display panel 30 or light incident on the optical member 500 disposed behind the display panel 30 passes through the display panel 30, the transmittance in the light-transmitting area TA may be high. Therefore, the recognition rate, sensing accuracy, etc. regarding the object 600 to be recognized by the optical member 500 may be increased. Specifically, when the common electrode 270 includes silver (Ag) and the optical member 500 includes an infrared camera, when the common electrode 270 in the second display area DA2 includes the patterned area 275, the transmittance of light in the infrared region may be further improved.

[0081] When the light-transmitting areas TA and the pixel areas PU2 are arranged in a regular arrangement in the second display area DA2, an image may be displayed in the second display area DA2 as in the first display area DA1. The second display area DA2 may provide functions other than image display by using the optical member 500.

[0082] The resolution of the second display area DA2 may be lower than that of the first display area DA1. However, when the pixel areas PU2 and the light-transmitting areas TA (i.e., the patterned areas 275 of the common electrode 270) are regularly and alternately arranged in the second display area DA2, the quality of the displayed image may be prevented from being deteriorated. For example, the pixel areas PU2 of the second display area DA2 may be as follows: Fig.13 , Fig.14 , Fig.15 and Fig.17 As shown in FIG. 1 , a red pixel R, a green pixel G, and a blue pixel B are included, and the shape of the pixel area PU2 can be substantially close to a square. Therefore, when such pixel areas PU2 are regularly arranged alternately with the light-transmitting areas TA, the transmittance can be increased while preventing degradation of image quality.

[0083] Reference Figure 5 , in a plan view, a portion of the common electrode 270 disposed in the pixel area PU2 surrounded by the light-transmitting area TA may be connected to the rest of the common electrode 270 by a bridge 70 included in the common electrode 270. The bridge 70 may prevent electrical disconnection therebetween. In the present exemplary embodiment, the bridge 70 may pass through a boundary between two unit light-transmitting areas TA, or may extend substantially in the first direction DR1 or the second direction DR2.

[0084] Portions of the common electrode 270 excluding the patterned region 275 of the common electrode 270 in the second display area DA2 may be alternately arranged with the unit light-transmitting areas TA in the first direction DR1 and the second direction DR2 .

[0085] The common electrode 270 disposed in the second display area DA2 may include an edge portion 270a disposed at a side not adjacent to the first display area DA1. In some embodiments, the edge portion 270a may be omitted.

[0086] Reference Figure 6 , except for the structure of the second display area DA2, the display device according to the present exemplary embodiment may be similar to the display device according to Figure 5 The display device of the exemplary embodiment shown in FIG. 1 is almost the same as that of FIG. 1 . The description will focus on the differences from the above-described embodiment, and the same description will not be repeated.

[0087] The light-transmitting area TA may be disposed between two pixel areas PU2 adjacent to each other in the first direction DR1 and the second direction DR2 in the second display area DA2. For example, the pixel areas PU2 and the light-transmitting area TA may be alternately arranged in the first direction DR1 and the second direction DR2. A plurality of pixel areas PU2 may be adjacent to each other in a diagonal direction.

[0088] In a plan view, a portion of the common electrode 270 disposed in the pixel area PU2 surrounded by the light-transmitting area TA may be connected to the rest of the common electrode 270 by a bridge 70 included in the common electrode 270, thereby preventing electrical disconnection therebetween. In the present exemplary embodiment, the bridge 70 may connect two portions of the common electrode 270 corresponding to two pixel areas PU2 adjacent to each other in one diagonal direction while crossing a boundary between two unit light-transmitting areas TA adjacent to each other in another diagonal direction.

[0089] In the second display area DA2, the patterned areas 275 of the common electrode 270 may be adjacent to each other in the diagonal direction. Therefore, portions other than the patterned areas 275 of the common electrode 270 in the second display area DA2 may be alternately arranged with the unit light-transmitting areas TA in the first direction DR1 and the second direction DR2, and may be arranged to be adjacent to each other in the diagonal direction. The unit light-transmitting area TA may not be disposed between them in the diagonal direction.

[0090] The size of one patterned area 275 may be the same as or similar to the size of one pixel area PU2.

[0091] against Figure 5 Other features described in the exemplary embodiments shown in the drawings may also be applied to Figure 6 An exemplary embodiment is shown in .

[0092] Reference Figure 7 , except for the structure of the second display area DA2, the display device according to the present exemplary embodiment may be similar to the display device according to Figure 5 The display devices of the exemplary embodiments shown in are almost the same.

[0093] By Figure 5 The pixel area PU2 located in the third and seventh columns of the second display area DA2 in FIG. 1 is moved down by one row or up by one row to obtain Figure 7 For example, the plurality of pixel areas PU2 disposed in different adjacent columns may be arranged in a zigzag form along the second direction DR2.
