Abstract

A display device includes: plural sub-pixels included in a main pixel, emitting light of different colors respectively; at least three apertures arranged so as to be aligned along one direction in the sub-pixel; and an aperture defining portion defining aperture lengths so that an aperture length of an aperture other than apertures at both edge portions along the one direction is longer than an aperture length of apertures at both edge portions along the one direction in the at least three apertures.

Claims (12)

1. A display device comprising:

a main pixel including a plurality of sub-pixels, the plurality of sub-pixels configured to emit light of different colors respectively, each of the plurality of sub-pixels including at least four apertures that are aligned along one direction, two of the at least four apertures being at respective opposite ends of the main pixel along the one direction; and

an aperture defining portion defining aperture lengths of the at least four apertures so that aperture lengths, along the one direction, of apertures other than the two apertures at the opposite ends of the main pixel are (i) longer than aperture lengths, along the one direction, of the two apertures at the opposite ends of the main pixel and (ii) equal to each other.

2. The display device according to claim 1 , wherein, when a distance between an aperture of the apertures other than the two apertures at the opposite ends of the main pixel and an adjacent aperture is “a”, and a distance between one of the two apertures at the opposite ends of the main pixel and another aperture at an end of another main pixel adjacent to the main pixel in the one direction is “b”, a<b is satisfied.

3. The display device according to claim 1 , wherein aperture lengths of the at least four apertures in the sub-pixel along a direction orthogonal to the one direction are equal.

4. The display device according to claim 1 , wherein light can be emitted through the at least four apertures.

5. The display device according to claim 1 , wherein the main pixel includes an organic electro luminescence (EL) layer for light emission.

6. An electronic apparatus comprising a display device in a main casing, wherein the display device includes:

(a) a main pixel including a plurality of sub-pixels, the plurality of sub-pixels configured to emit light of different colors respectively, each of the plurality of sub-pixels including at least four apertures that are aligned along one direction, two of the at least four apertures being at respective opposite ends of the main pixel along the one direction; and

(b) an aperture defining portion defining aperture lengths of the at least four apertures so that aperture lengths, along the one direction, of apertures other than the two apertures at the opposite ends of the main pixel are (i) longer than aperture lengths, along the one direction, of the two apertures at the opposite ends of the main pixel and (ii) equal to each other.

7. The electronic apparatus according to claim 6 , wherein light can be emitted through the at least four apertures.

8. The electronic apparatus according to claim 6 , wherein the main pixel includes an organic electro luminescence (EL) layer for light emission.
