Abstract

A display panel includes a unit for each sub-pixel, the unit including a plurality of openings, the unit having an array structure in which the openings are arranged in a close packing manner. In the array structure of the unit, when a single virtual opening is placed within a peripheral region of the unit, and a center of the virtual opening and centers of a plurality of openings located adjacent to the virtual opening are connected to one another by straight lines, only one basic figure for the arrangement in the close packing manner is created but two basic figures therefor are not created.

Claims

1. A display panel comprising

a unit for each sub-pixel, the unit including a plurality of openings, the unit having an array structure in which the openings are arranged in a close packing manner,

wherein in the array structure of the unit, when a single virtual opening is placed within a peripheral region of the unit, and a center of the virtual opening and centers of a plurality of openings located adjacent to the virtual opening are connected to one another by straight lines, only one basic figure for the arrangement in the close packing manner is created but two basic figures therefor are not created.

2. The display panel according to claim 1, wherein

each sub-pixel includes a self-luminous device and a plurality of reflection structures decreasing a divergence angle of light emitted from the self-luminous device, and

each of the reflection structures includes the openings and a reflection surface reflecting light emitted from the self-luminous device.

3. The display panel according to claim 2, wherein

the self-luminous device has a structure in which an organic layer is sandwiched by a reflective electrode and a transparent electrode,

the reflection structures are formed on an upper surface of the reflective electrode while being in contact with the upper surface of the reflective electrode, and

the organic layer and the transparent electrode are formed at least in bottoms of the openings.

4. The display panel according to claim 3, wherein the reflective electrode has a planar shape corresponding to a planar shape of the unit.

5. The display panel according to claim 4, wherein each sub-pixel has a planar shape corresponding to the planar shape of the reflective electrode.

6. The display panel according to claim 3, wherein the unit has a hexagonal shape.

7. The display panel according to claim 3, wherein the unit has a trapezoidal shape.

8. The display panel according to claim 3, wherein the unit has an inclined quadrangular shape.

9. The display panel according to claim 1, wherein the basic figure for the arrangement of the close packing manner is a triangular shape.

10. The display panel according to claim 1, wherein each of the openings has a point-symmetrical shape.

11. A display including a display panel and a drive circuit driving the display panel, the display panel comprising

a unit for each sub-pixel, the unit including a plurality of openings, the unit having an array structure in which the openings are arranged in a close packing manner,

wherein in the array structure of the unit, when a single virtual opening is placed within a peripheral region of the unit, and a center of the virtual opening and centers of a plurality of openings located adjacent to the virtual opening are connected to one another by straight lines, only one basic figure for the arrangement in the close packing manner is created but two basic figures therefor are not created.

12. An electronic unit with a display, the display including a display panel and a drive circuit driving the display panel, the display panel comprising

a unit for each sub-pixel, the unit including a plurality of openings, the unit having an array structure in which the openings are arranged in a close packing manner,

wherein in the array structure of the unit, when a single virtual opening is placed within a peripheral region of the unit, and a center of the virtual opening and centers of a plurality of openings located adjacent to the virtual opening are connected to one another by straight lines, only one basic figure for the arrangement in the close packing manner is created but two basic figures therefor are not created.
