Abstract

A display device includes plural unit areas each of which includes low definition pixels as sub-pixels larger than a specified standard and high definition pixels as sub-pixels smaller than the specified standard and which are regularly arranged. The low definition pixels include a blue pixel and a red pixel, and the high definition pixels include a white pixel and a green pixel.

Claims (44)

1. A display device comprising:

low definition pixels as sub-pixels, each of the low definition pixels having an area larger than a specified standard area;

high definition pixels as sub-pixels, each of the high definition pixels having an area smaller than the specified standard area; and

transparent pixels larger than the low definition pixels,

wherein

the low definition pixels, the high definition pixels, and the transparent pixels are included in each of unit areas which are regularly arranged,

the low definition pixels include blue pixels and red pixels,

the high definition pixels include green pixels,

each of the red, green, and blue pixels includes an organic light emitting element and a transistor connected to the organic light emitting element,

none of the transparent pixels includes any organic light emitting element or any transistor,

none of the red, green, and blue pixels overlaps with any of the transparent pixels, and

none of the transparent pixels is configured to be controlled by any switch element in each of the transparent pixels.

2. The display device according to claim 1 , further comprising:

an element substrate on which the organic light emitting element and the transistor is formed; and

an opposite substrate facing the element substrate,

wherein the transparent pixels each are configured to transmit light coming into the element substrate and going outside of the opposite substrate.

3. A display device comprising:

a plurality of first pixels each of which includes a red pixel or a blue pixel and has a first area;

a plurality of second pixels each of which includes a green pixel and has a second area; and

a plurality of third pixels each of which includes a transparent pixel and has a third area,

wherein

the first area is larger than the second area,

the third area is larger than the first area,

each of the plurality of first and second pixels includes an organic light emitting element and a transistor connected to the organic light emitting element,

none of the plurality of third pixels includes any organic light emitting element or any transistor,

none of the plurality of first and second pixels overlaps with any of the plurality of third pixels,

the plurality of first and second pixels are arranged in a matrix in plan view along two orthogonal axes, the two orthogonal axes extending in a first direction, in a second direction perpendicular to the first direction, in a third direction opposite to the first direction, and in a fourth direction opposite to the second direction,

each of the plurality of first pixels is adjacent to respective ones of the plurality of third pixels in the first direction, the second direction, the third direction, and the fourth direction in plan view, and

each of the plurality of second pixels is adjacent to respective ones of the plurality of third pixels in the first direction, the second direction, the third direction, and the fourth direction in plan view.

4. The display device according to claim 3 , further comprising:

an element substrate on which the organic light emitting element and the transistor is formed; and

an opposite substrate facing the element substrate,

wherein the transparent pixel is configured to transmit light coming into the element substrate and going outside of the opposite substrate.

5. The display device according to claim 3 , wherein the plurality of second pixels are provided in more number than each of the red pixel and the blue pixel.

6. The display device according to claim 3 , further comprising:

an element substrate on which the organic light emitting element and the transistor is formed; and

an opposite substrate facing the element substrate,

wherein

the element substrate has a first side, a second side, a third side, and a fourth side in plan view,

the first side runs along a fifth direction, the second side runs along a sixth direction, the third side runs along a seventh direction, the fourth side runs along an eighth direction, the sixth direction is perpendicular to the fifth direction, the seventh direction is an opposite direction to the fifth direction, the eighth direction is an opposite direction to the sixth direction, and each of the fifth and seventh directions is perpendicular to each of the sixth and eighth directions, and

each of the fifth, sixth, seventh, and eighth directions differs from each of first, second, third, and fourth directions.

7. The display device according to claim 3 , wherein

a central portion of each of the plurality of first pixels is adjacent to respective ones of the plurality of third pixels in the first direction, the second direction, a third direction, and a fourth direction in plan view, and

a central portion of each of the plurality of second pixels is adjacent to respective ones of the plurality of third pixels in the first direction, the second direction, a third direction, and a fourth direction in plan view.
