Abstract

A display device which can relax a discontinuity feeling in displaying is provided. The display device according to the present invention operated by using a display method in which a lot of pixels having aperture parts are arranged and in which the respective pixels are controlled in a brightness to display images comprises such a pixel structure and a pixel array that concave parts are formed in different four directions and the other directions which are lateral directions on the same plane of the aperture parts of the pixels described above and that the aperture parts of the adjacent pixels are arranged to the concave parts described above.

Claims

1. A display device operated by using a display method in which a lot of pixels having aperture parts are arranged and in which the respective pixels are controlled in a brightness to display images, comprising a pixel structure and a pixel array in which irregular parts are formed to plural different directions from the centers of the aperture parts of the pixels described above on the same plane and in which the irregular parts of the pixels are arranged in combination with irregular parts of aperture parts of the adjacent pixels.

2. The display device according to claim 1, comprising such a pixel structure and a pixel array that the pixels described above are constituted in an array in which they are adjacent and arranged in point symmetry or line symmetry and that lines drawn for connecting boundaries between the pixels are not straight lines in any directions.

3. The display device according to claim 1, wherein the aperture parts of the respective pixels described above are characterized by having a cross form, a double cross form or a form based on cross forms.

4. The display device according to claim 1, wherein the pixel structure and the pixel array described above comprise such a structure and an array that the pixels having the aperture parts in which the irregular parts described above are formed in the plural directions and the pixels arranged by tilting these pixels by 90 degrees are combined and arranged so that they are adjacent to each other.

5. The display device according to claim 1, wherein the pixel structure and the pixel array described above comprise a structure and an array in which pixels having a form of a mark <

and pixels having a form of a mark >

are combined and arranged in point symmetry in a lateral line direction or a vertical line direction.

6. The display device according to claim 1, wherein in a region in which adjacent two pixels are spatially mixed, the closer the pixel adjacent thereto is to an area centroid of the one pixel, the larger the area occupancy ratio of the one pixel to the pixel adjacent thereto is.
