Organic electroluminescent light emitting display device

An electro-optical device includes a transmission polarization axis conversion unit having a first surface and a second surface, an absorption polarization unit having transmission polarization axis in a first direction and having absorption polarization axis in a second direction, and a reflective polarization unit including a region having a transmission polarization axis in the first direction and a reflective polarization axis in the second direction, and an opening. The transmission polarization axis conversion unit can switch a first/second state, the first state is an incident light entering the first surface from the absorption polarization unit is converted into a first outgoing light of linearly polarized light in the second direction, and the first outgoing light is emitted from the second surface, the second state is the incident light converted into a second outgoing light of linearly polarized light in the first direction and emitted from the second surface.

Electro-optical device

A display device includes a plurality of pixels each having a plurality of light-emitting regions including at least a first light-emitting region of a first color, a second light-emitting region of a second color, and a third light-emitting region of a third color and a light-transmitting region. Visibility of the first color is higher than visibility of the second color. The plurality of light-emitting regions are divided into a first group including the first light-emitting region and a second group including the second light-emitting region. The first light-emitting region is adjacent to the second light-emitting region. The light-transmitting region is located between the first light-emitting region and the second light-emitting region. The light-transmitting region is not located in a region between light-emitting regions adjacent to each other in the first group and in a region between light-emitting regions adjacent to each other in the second group.

Display device

In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.

The divided regions include first regions and second regions that are different from each other in widths in at least one of the X-direction and the Y-direction.

In a display device, light emitting areas and colored areas each have a predetermined planar shape having no rotational symmetry so that rotation of the area by an angle greater than or equal to 0&#xb0; but smaller than 360&#xb0; does not produce an initial shape of the area and are so arranged as to have different types of rotation angle. The colored areas are grouped based on a set of the colored areas of colors different from one another to forma plurality of full-color pixels. The full-color pixels are so arranged that the rotation angle of the colored areas of the same color have different types.
