Display device with clearance
A display device is provided, in which view-angle dependence of chromaticity of white or an intermediate color may be reduced. The display device includes: a pair of opposed substrates; a light blocking film provided on one of the pair of substrates while having a plurality of openings; and a plurality of self-luminous elements provided on the other of the pair of substrates, each of the self-luminous elements having an emission region facing each of the openings, and having an emission color different from an emission color of another element, at least one self-luminous element being different from other self-luminous elements in clearance in a display plane direction from an end of the emission region to an opening of the light blocking film.
1. A display device comprising:
a pair of opposed substrates;
a light blocking layer provided over one substrate of the pair of substrates while having a plurality of openings; and
a plurality of self-luminous elements provided on the other substrate of the pair of substrates, each of the self-luminous elements having an emission region facing each of the openings, and having an emission color different from an emission color of another element, at least one self-luminous element being different from other self-luminous elements in clearance in at least one of a display plane horizontal direction and a display plane vertical direction from an edge of the emission region to an edge of a corresponding opening of the light blocking layer,
wherein a difference in clearance includes at least:
(i) a first length of non-overlapping separation between a first edge of a first opening of the light blocking layer and a second edge of a corresponding first emission region, and
(ii) a second length of non-overlapping separation between a third edge of a second opening of the light blocking layer and a fourth edge of a corresponding second emission region,
wherein the first length is different than the second length.
2. The display device according to claim 1 ,
wherein a dimension in a vertical direction in a display plane of the emission region is larger than a dimension in a horizontal direction in the display plane of the emission region, and
the clearance is a distance in the horizontal direction in the display plane.
3. The display device according to claim 2 ,
wherein the one self-luminous element is large in the dimension in the horizontal direction in the display plane of the emission region, and small in the clearance compared with the self-luminous elements other than the one self-luminous element.
4. The display device according to claim 1 ,
wherein the clearance is continuously changed within the one self-luminous element.
5. The display device according to claim 1 ,
wherein color filters are provided in the openings of the light blocking layer, respectively.
6. The display device according to claim 1 ,
wherein, at an oblique viewing angle, a first self-luminous element with the first length of separation has a first light blocking area,
wherein, at the oblique viewing angle, a second self-luminous element with the second length of separation has a second light blocking area,
wherein the first emission region, which corresponds to the first self-luminous element, has a first emission region area,
wherein the second emission region, which corresponds to the second self-luminous element, has a second emission region area, and
wherein a first ratio of the first light blocking area to the first emission region area is different from a second ratio of the second light blocking area to the second emission region area.
