Document Type and Number:

Japanese Patent JP3791744

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To prevent luminous elements of equal luminous intensity from being unevenly distributed and to prevent generation of a linear pattern or the like by making arrangement of plural luminous elements different in adjacent pixels and sub-pixels.
SOLUTION: In a display device which is provided with pixels formed to a matrix shape, two luminous elements 11, 12 as display elements having different luminous intensity are arranged at a pixel. Arrangement of two luminous elements 11, 12 at each pixel is in transposition relation to each other when pixels adjoining in a transverse direction (a direction orthogonally crossing an aligning direction of luminous elements in an image) are compared. In such arrangement, when the same intermediate tone is expressed at each pixel, light emitting luminous elements are uniformly dispersed and generation of linear patterns is prevented. Otherwise, it can be said that linear pattern is hard to visually recognize since spatial frequency of a pattern in a transverse direction exceeds visibility limit.
