According to an embodiment, the light-blocking member (403) may include a plurality of open areas (O1, O2, and O3) for placing a plurality of color filters (CF1, CF2, and CF3), respectively, and an area (e.g., the light-blocking member (403)) excluding the plurality of open areas (O1, O2, and O3) may block light incident on the first substrate (401). In an embodiment, in a part of the display (210) (e.g., an area A including one pixel in FIG. 3), the light-blocking member (403) may include a first open area (O1) having a first size and a plurality of second open areas (O2 and O3) having a second size. For example, the second size of each of the plurality of second open areas (02 and 03) may be the same as each other and may be larger than the first size of the first open area (O1).

[0061] According to one embodiment, in process step 420, a plurality of color filters (CF1, CF2, and CF3) may be arranged in each of a plurality of open areas (O1, O2, and O3) of the light-shielding member (403). For example, a blue first color filter (CF1) may be arranged in a first open area (O1) among the plurality of open areas (O1, O2, and O3), and a plurality of second color filters (CF2 and CF3) may be arranged in each of the plurality of second open areas (O2 and O3). In one embodiment, the plurality of second color filters (CF2 and CF3) may include a red color filter (CF2) and a green color filter (CF3). For example, in each of the plurality of second open areas (O2 and O3), color filters (CF2 and CF3) may be arranged in the order of red and green, or color filters (CF3 and CF2) may be arranged in the order of green and red.

[0062] In one embodiment, each of the plurality of color filters (CF1, CF2, and CF3) may have a size corresponding to an open area of ​​the light blocking member (403) in which the color filter is to be arranged. For example, the first color filter (CF1) arranged in the first open area (O1) may have a first size corresponding to (or substantially identical to) the first size of the first open area (O1), and the plurality of second color filters (CF2 and CF3) arranged in each of the plurality of second open areas (O2 and O3) may have a second size corresponding to (or substantially identical to) the second sizes of the plurality of second open areas (O2 and O3). Based on this, the size of each of the plurality of second color filters (CF2 and CF3) arranged in each of the plurality of second open areas (O2 and O3) may be larger than the size of the first color filter (CF1) arranged in the first open area (O1). In one embodiment, a combination of a light-shielding member (403) and a plurality of color filters (CF1, CF2, and CF3) arranged in a plurality of open areas (O1, O2, and O3) of the light-shielding member (403) may be referred to as a light-shielding layer or a color filter layer.

[0063] According to one embodiment, in process step 430, a partition wall (405) may be placed on the light-shielding member (403). In one embodiment, a planarization layer (not shown) for planarizing the step between the plurality of color filters (CF1, CF2, and CF3) and the light-shielding member (403) may be placed on the light-shielding member (403), and the partition wall (405) may be placed on the planarization layer.

[0064] In one embodiment, the partition wall (405) may form (or define) a plurality of pixel areas (PA1, PA2, and PA3). For example, the partition wall (405) may be formed to surround a first color filter (CF1) disposed in a first open area (O1) to define a first pixel area (PA1), and may be formed to surround a plurality of second color filters (CF2 and CF3) disposed in each of a plurality of second open areas (O1 and O2) to define a plurality of second pixel areas (PA2 and PA3). In one embodiment, the partition wall (405) may be formed of a light-shielding or light-reflective material.

[0065] In one embodiment, the plurality of pixel areas (PA1, PA2, and PA3) formed (or defined) by the partition wall (405) may correspond to each of the plurality of sub-pixels (e.g., the plurality of sub-pixels (P1, P2, and P3) of FIG. 3) included in the pixel (e.g., the pixel (P) of FIG. 3). For example, the first pixel area (PA1) may correspond to the first sub-pixel (P1) expressing blue, and each of the plurality of second pixel areas (PA2 and PA3) may correspond to the second sub-pixel (P2) expressing red and the third sub-pixel (P3) expressing green.

[0066] According to one embodiment, the depth of each of the plurality of pixel areas (PA1, PA2, and PA3) formed (or defined) by the partition wall (405) may be the same. For example, the height of the partition wall (405) forming the first pixel area (PA1) and the height of the partition wall (405) forming each of the plurality of second pixel areas (PA2 and PA3) may be the same.

[0067] In one embodiment, the plurality of second pixel areas (PA2 and PA3) may have the same volume as each other and may have a different volume from the volume of the first pixel area (PA1). For example, the volume of each of the plurality of second pixel areas (PA2 and PA3) may be larger than the volume of the first pixel area (PA1). In one embodiment, the plurality of pixel areas (PA1, PA2, and PA3) may share at least a portion of the partition wall (405) with an adjacent pixel area.

[0068] According to one embodiment, in process step 440, color conversion members (407R and 407G) may be placed in some of the plurality of pixel areas (PA1, PA2, and PA3) formed (or defined) by the partition wall (405). In addition, members having different characteristics from the color conversion members (407R and 407G) (e.g., transparent members (407C)) may be placed in other parts of the plurality of pixel areas (PA1, PA2, and PA3) where the color conversion members (407R and 407G) are not placed.

[0069] Referring to FIG. 5, a color conversion member (407R and 407G) may be printed on each of a plurality of second pixel areas (PA2 and PA3) formed by the partition wall (405) based on an electrohydrodynamic (EHD) spinning process. For example, ink including a red quantum dot or a red fluorescent material ejected from a nozzle (501) may be applied to any one of the plurality of second pixel areas (PA2 and PA3) (e.g., pixel area (PA2)) and then cured to form a color conversion member (407R) that converts light energy incident on the corresponding pixel area (PA2) into the red light. Similarly, in another one of the plurality of second pixel areas (PA2 and PA3) (e.g., pixel area PA3), ink including a green quantum dot or a green fluorescent material ejected from a nozzle (501) may be applied and then cured to form a color conversion member (407G) that converts light energy incident on the corresponding pixel area (PA3) into the green light. According to one embodiment, in the EHD spinning process, the nozzle (501) may move in a first direction (e.g., +Y and -Y directions), and the ink ejected from the nozzle (501) may flow (e.g., flow in a second direction (+X and -X directions)) inside the plurality of second pixel areas (PA2 and PA3) by the partition wall (405) before being cured, and may be filled into the plurality of second pixel areas (PA2 and PA3). In one embodiment, a transparent member (407C) may be formed in the first pixel area (PA1) based on a photolithography process. For example, an optically transparent transparent member (407C) (e.g., resin) may be formed in the first pixel area (PA1).In one embodiment, the combination of a partition wall (405), a transparent member (407C) disposed in a first pixel area (PA1) of the partition wall (405), and color conversion members (407R and 407G) disposed in each of a plurality of second pixel areas (PA2 and PA3) of the partition wall (405) may be referred to as a partition wall layer or a color conversion layer.

[0070] According to one embodiment, in process step 450, a plurality of light sources (409) may be arranged in each of a plurality of pixel areas (PA1, PA2, and PA3) formed by the partition walls (405). For example, each of the plurality of light sources (409) may be arranged on color conversion members (407R and 407G) and transparent members (407C) formed in the plurality of pixel areas (PA1, PA2, and PA3) so as to be aligned with a plurality of color filters (CF1, CF2, and CF3) corresponding to each of the plurality of pixel areas (PA1, PA2, and PA3). In an alternative embodiment, the plurality of light sources (409) may be arranged on a second substrate (e.g., a thin film transistor (TFT) circuit board) for driving the plurality of light sources (409), and the second substrate may be arranged on the partition wall layer or the color conversion layer using an optically transparent adhesive member. In one embodiment, the plurality of light sources (409) may include organic light emitting diodes (OLEDs) and / or micro LEDs that provide light in the blue wavelength band.

[0071] FIG. 6 is a plan view illustrating a portion of a display according to one embodiment.

[0072] In the embodiment of FIG. 6, a portion of the display may be referred to as region A, which includes one pixel of the display (e.g., display (210)) illustrated in FIG. 3.

[0073] Referring to FIG. 6, the sizes of each of the plurality of second color filters (CF2 and CF3) included in the display (210) according to one embodiment may be different from the size of the first color filter (CF1). For example, the first open area (O1) of the light-blocking member (e.g., the light-blocking member (403) of FIG. 4B) may have a first size, and the first color filter (CF1) disposed in the first open area (O1) may have a first size corresponding to (or substantially identical to) the first size. In addition, for example, each of the plurality of second open areas (O2 and O3) of the light-blocking member (403) may have a second size larger than the first size, and the plurality of second color filters (CF2 and CF3) disposed in each of the plurality of second open areas (O2 and O3) may have a second size corresponding to the second size.

[0074] In one embodiment, the areas or sizes of the plurality of pixel areas (PA1, PA2, and PA3) formed (or defined) by the partition wall (405) may be at least partially different. For example, when viewed in plan view, the size of the first pixel area (PA1) may have a first size corresponding to (or substantially the same as) the first size of the first open area (O1) or the first color filter (CF1). Also, for example, when viewed in plan view, the size of each of the plurality of second pixel areas (PA2 and PA3) may have a third size greater than the second sizes of the plurality of second open areas (O2 and O3) or the plurality of second color filters (CF2 and CF3). In one embodiment, a light blocking member (403) may be positioned in an area of ​​each of the plurality of second pixel areas (PA2 and PA3) having the third size when viewed from a plane, which does not correspond to the plurality of second open areas (O2 and O3) having the second size or the plurality of second color filters (CF2 and CF3). On the other hand, an area of ​​the first pixel area (PA1) having the first size may be occupied by the first open area (O1) or the first color filter (CF1) having the same first size, and thus the light blocking member (403) may not be positioned therein.

[0075] In one embodiment, each of the plurality of second open areas (O2 and O3) may have a first length (L1 or L3) in a first direction (e.g., +Y and -Y directions) that is different from a second length (L2 or L4) in a second direction (e.g., +X and -X directions) that is perpendicular to the first direction. For example, the first length (L1 or L3) of each of the plurality of second open areas (O2 and O3) may be longer than the second length (L2 or L4).

[0076] According to one embodiment, the first pixel area (PA1) may be located between a plurality of second pixel areas (PA2 and PA3). For example, the partition wall (405) may form (or define) a plurality of second pixel areas (PA2 and PA3) having a shape that is symmetrical with respect to an imaginary line that is parallel to the first direction (e.g., +Y and -Y directions) and located between the second pixel areas (PA2 and PA3), and the first pixel area (PA1) may be formed in an area between the plurality of second pixel areas (PA2 and PA3) formed by the symmetrical shapes.

[0077] FIG. 7 is a plan view illustrating a second pixel area and a third pixel area of ​​a portion of a display according to one embodiment.

[0078] In the embodiment of FIG. 7, a portion of the display may be referred to as region A, which includes one pixel of the display (e.g., display (210)) illustrated in FIG. 3.

[0079] Referring to FIG. 7, each of the plurality of second pixel areas (PA2 and PA3) included in the display (210) according to one embodiment may include a first area (701 or 705) and a second area (703 or 707). For example, the first area (701 or 705) and the second area (703 or 707) of each of the plurality of second pixel areas (PA2 and PA3) are areas that are distinguished by their shapes, are not physically blocked by the partition wall (405), and may be open to each other in the second direction (e.g., +X and -X directions).

[0080] In one embodiment, each of the first regions (701 or 705) of the plurality of second pixel regions (PA2 and PA3) may have a first length (L5 or L7) in a first direction (e.g., +Y and -Y directions), and each of the second regions (703 or 707) of the plurality of second pixel regions (PA2 and PA3) may have a second length (L6 or L8) longer than the first length (L5 or L7) in the first direction (e.g., +Y and -Y directions). In various embodiments, the first region (701 or 705) and the second region (703 or 707) may have the same or different lengths in a second direction (e.g., +X and -X directions) perpendicular to the first direction.

[0081] In one embodiment, the first region (701 or 705) of each of the plurality of second pixel regions (PA2 and PA3) may be formed to protrude from the second region (703 or 707) of the corresponding second pixel region (PA2 or PA3) toward the neighboring second pixel region (PA3 or PA2). For example, the first region (701) of the second pixel region (PA2) may be formed to protrude from the second region (703) toward the second pixel region (PA3) in a second direction (e.g., the -X direction), and the first region (705) of the second pixel region (PA3) may be formed to protrude from the second region (707) toward the second pixel region (PA2) in a second direction (e.g., the +X direction). Based on this, each of the plurality of second pixel areas (PA2 and PA3) may have a “P” shape, and a first area (701 or 705) of each of the plurality of second pixel areas (PA2 and PA3) may overlap at least a portion of the first pixel area (PA1) in a first direction (e.g., +Y and -Y directions). The first areas (701 and 705) of the plurality of second pixel areas (PA2 and PA3) may not overlap with the first pixel area (PA1) in a second direction (e.g., +X and -X directions), whereas portions (e.g., first portions) of the second areas (703 and 707) may overlap with the first pixel area (PA1) in the second direction. The first pixel area (PA1) may be located within a space formed by the first areas (701 and 705) and the second areas (703 and 707).

[0082] In one embodiment, the plurality of light sources (409) arranged in each of the plurality of pixel areas (PA1, PA2, and PA3) may have a length direction corresponding to a first direction (e.g., +Y and -Y directions). For example, a first length (L9) of each of the plurality of light sources (409) in the first direction (e.g., +Y and -Y directions) may be longer than a second length (L10) of each of the plurality of light sources (409) in a second direction (e.g., +X and -X directions) perpendicular to the first direction (e.g., +Y and -Y directions).

[0083] Referring to FIGS. 6 and 7, when viewed in plan view, the second color filter (CF2) may overlap with the first region (701), another portion (e.g., the second portion) of the second region (703) may overlap with the first region (701) in the second direction, the second color filter (CF3) may overlap with the first region (705), and another portion (e.g., the second portion) of the second region (707) may overlap with the first region (705) in the second direction. When viewed in plan view, portions (first portions) of the second regions (703 and 707) that overlap with the first pixel region (PA1) in the second direction may not overlap with the plurality of second color filters (CF2 and CF3).

[0084] In one embodiment, when viewed in a plan view, the size and shape of the color conversion members (407R and 407G) may be the same as the size and shape of the plurality of second pixel areas (PA2 and PA3), respectively, and when viewed in a plan view, the size and shape of the transparent member (407C) may be the same as the size and shape of the first pixel area (PA1). Accordingly, the descriptions regarding the size and shape of the plurality of second pixel areas (PA2 and PA3) and the first pixel area (PA1) may also be applied to the size and shape of the color conversion members (407R and 407G) and the transparent member (407C), respectively.

[0085] FIG. 8 is a cross-sectional view illustrating various directions of a portion of a display according to one embodiment. FIG. 9 is a cross-sectional view illustrating one direction of a portion of a display according to another embodiment.

[0086] In the embodiments of FIG. 8 and FIG. 9, a portion of the display may be referred to as region A, which includes one pixel of the display (e.g., display (210)) illustrated in FIG. 3.

[0087] Referring to FIG. 8, the centers of the plurality of second color filters (CF2 and CF3) included in the display (210) according to one embodiment may be positioned on the same line (e.g., line AA'). For example, the centers (C2 and C3) of each of the plurality of second color filters (CF2 and CF3) may be positioned on a first line (e.g., line AA') extending in a second direction (e.g., +X and -X directions). In one embodiment, the center (C1) of the first color filter (CF1) may be positioned on a second line (e.g., line BB') that is different from and parallel to the first line (e.g., line AA'). In one embodiment, the plurality of color filters (CF1, CF2, and CF3) may not overlap each other when viewed in a plane. Based on this, in the cross section of the display (210) for the first line (e.g., line AA'), a plurality of second color filters (CF2 and CF3) having a second size, color conversion members (407R and 407G) inside a plurality of second pixel areas (e.g., a plurality of second pixel areas (PA2 and PA3) of FIG. 7) in which each of the plurality of second color filters (CF2 and CF3) is arranged, and a plurality of light sources (409) corresponding to each of the plurality of second pixel areas (PA2 and PA3) may be positioned. In addition, in the cross section of the display (210) for the second line (e.g., BB' line), a first color filter (CF1) having a first size smaller than the second size, a transparent member (407C) inside a first pixel area (e.g., the first pixel area (PA1) of FIG. 7) in which the first color filter (CF1) is arranged, color conversion members (407R and 407G), and a light source (409) corresponding to the first pixel area (PA1) may be positioned.In addition, in the cross section of the display (210) for the third line (e.g., CC' line) in the first direction (e.g., +Y and -Y directions) where the center (C2 or C3) of one of the plurality of second color filters (CF2 and CF3) is located, a second color filter (CF2 or CF3) having a second size, a color conversion member (407R or 407G) inside a second pixel area (PA2 or PA3) in which the second color filter is arranged, and a light source (409) corresponding to the second pixel area (PA2 or PA3) may be located.

[0088] According to various examples, a portion of the light in the blue wavelength band provided from the plurality of light sources (409) corresponding to each of the plurality of second pixel areas (PA2 and PA3) may be absorbed by the partition walls (405) forming (or defining) the plurality of second pixel areas (PA2 and PA3) and dissipated as heat, or may be absorbed by the color conversion members (407R and 407G) arranged in the plurality of second pixel areas (PA2 and PA3) and dissipated as heat. That is, when the color conversion members (407R and 407G) arranged in the plurality of second pixel areas (PA2 and PA3) have the same size or volume as the transparent member (407C) arranged in the first pixel area (PA1), each of the second sub-pixels (e.g., the second sub-pixel (P2) of FIG. 3) and the third sub-pixels (e.g., the third sub-pixel (P3) of FIG. 3) corresponding to each of the plurality of second pixel areas (PA2 and PA3) may have lower light efficiency compared to the first sub-pixel (e.g., the first sub-pixel (P1) of FIG. 3) corresponding to the first pixel area (PA1). In addition, when the plurality of second color filters (CF2 and CF3) corresponding to the plurality of second pixel areas (PA2 and PA3) have the same size as the first color filter (CF1) corresponding to the first pixel area (PA1), since the plurality of light sources (409) provide blue wavelength light, each of the second sub-pixels (P2) and the third sub-pixels (P3) corresponding to each of the plurality of second pixel areas (PA2 and PA3) may have lower light efficiency compared to the first sub-pixel (P1) corresponding to the first pixel area (PA1).

[0089] On the other hand, the display (210) according to one embodiment can compensate for light energy dissipated in the partition (405) and / or the color conversion members (407R and 407G) by increasing the amount of color-converted light (e.g., red or green light) incident on the color conversion members (407R and 407G) based on a structure in which the size or volume of the color conversion members (407R and 407G) (or the plurality of second pixel areas (PA2 and PA3) in which the color conversion members (407R and 407G) are arranged) is increased compared to the transparent member (407C) (or the first pixel area (PA1) in which the transparent member (407C) is arranged). In addition, the display (210) according to one embodiment can compensate for light energy dissipated in the partition wall (405) and / or the color conversion member (407R and 407G) by increasing the amount of light in the blue wavelength band incident on the plurality of second color filters (CF2 and CF3) based on a structure in which the size of the plurality of second color filters (CF2 and CF3) on which light converted by the color conversion member (407R and 407G) is incident is increased compared to the first color filter (CF1) on which blue light transmitted through the transparent member (407C) is incident.

[0090] Referring to FIG. 9, a plurality of second color filters (CF2 and CF3) corresponding to each of a plurality of second pixel areas (e.g., the plurality of second pixel areas PA2 and PA3 of FIG. 7) included in a display (210) according to an embodiment may have a second size that is larger than a first size of a first color filter (CF1) corresponding to a first pixel area (e.g., the first pixel area PA1 of FIG. 7). According to an embodiment, with respect to a first line (e.g., line AA') in a second direction (e.g., +X and -X directions) where the centers (C2 and C3) of each of the plurality of second color filters (CF2 and CF3) are located, a second direction length forming the second size of each of the plurality of second color filters (CF2 and CF3) may be longer than a second direction length of each of the plurality of second pixel areas (PA2 and PA3). Based on this, in the cross-section of the display (210) for the first line (e.g., line AA'), each of the plurality of second color filters (CF2 and CF3) may overlap at least a portion of the partition (405) forming (or defining) the plurality of second pixel areas (PA2 and PA3).

[0091] Fig. 10 is a plan view illustrating a printing process of a transparent member according to one embodiment. Fig. 11 is a drawing illustrating a cross-section in one direction of a portion of a display according to one embodiment.

[0092] Referring to FIGS. 10 and 11, a display (210) according to an embodiment may include an empty space (1005) formed between adjacent sub-pixels of a plurality of pixels (1001 and 1003). For example, the empty space (1005) may be formed in a partition (405) between adjacent sub-pixels of the plurality of pixels (1001 and 1003) (e.g., a third sub-pixel (P3) of the pixel (1001) and a second sub-pixel (P2) of the pixel (1003)) on the same line as a first sub-pixel (P1) of each of the plurality of pixels (1001 and 1003). According to one embodiment, in a process of printing a transparent member (407C) in a first pixel area (PA1) corresponding to a first sub-pixel (P1) of each of the plurality of pixels (1001 and 1003), a transparent member (407C) may also be printed in the empty space (1005). For example, in a structure of a display (210) including an empty space (1005), a transparent member (407C) may be printed in the first pixel area (PA1) based on an electrohydrodynamic (EHD) spinning process directed in a second direction (e.g., +X and -X directions), and a transparent member (407C) based on the EHD spinning process may also be printed in the empty space (1005) on a line corresponding to the first pixel area (PA1).

[0093] In one embodiment, as illustrated in the drawing above in FIG. 11, when a transparent member (407C) is printed in a first pixel area (PA1) corresponding to a first sub-pixel (P1) and the empty space (1005) by an EHD spinning process in a second direction (e.g., +X and -X directions), and then color conversion members (407R and 407G) are printed in a first direction (e.g., +Y and -Y directions) perpendicular to the second direction in a plurality of second pixel areas (PA2 and PA3) corresponding to each of the second sub-pixels (P2) and the third sub-pixel (P3) by an EHD spinning process, the transparent member (407C) may be positioned between the light-blocking member (403) and the color conversion member (407R or 407G) in each of the plurality of second pixel areas (PA2 and PA3). Conversely, as shown in the drawing below in FIG. 11, when color conversion members (407R and 407G) are printed in a first direction (e.g., +Y and -Y directions) in a plurality of second pixel areas (PA2 and PA3) corresponding to the second sub-pixel (P2) and the third sub-pixel (P3) respectively by an EHD spinning process, and then a transparent member (407C) is printed in a second direction (e.g., +X and -X directions) in a first pixel area (PA1) corresponding to the first sub-pixel (P1) and the empty space (1005) by an EHD spinning process, the transparent member (407C) in each of the plurality of second pixel areas (PA2 and PA3) may be positioned to cover at least a portion of the partition wall (405) forming the corresponding second pixel area (PA2 or PA3) and at least a portion of the color conversion member (407R or 407G) printed in the corresponding second pixel area (PA2 or PA3).

[0094] According to various embodiments, the empty space (1005) may be connected to a first pixel area (PA1) corresponding to a first sub-pixel (P1) of each of the plurality of pixels (1001 and 1003). In this case, the first pixel area (PA1) corresponding to the first sub-pixel (P1) of each of the plurality of pixels (1001 and 1003) may extend in the second direction (e.g., +X and -X directions) without being separated by the partition wall (405).
