Abstract
A color display device of the type having a plurality of light-transmissible and non-light-emitting picture elements such as liquid crystal display. The plurality of non-light-emitting picture elements for red, green and blue are arranged in checked arrangement. The number of the picture elements for green is larger than each of the other picture elements for red and blue and the total intensity of transmitting light at each of picture elements for said three colors is equal to each of the other picture elements, respectively. The number of picture elements for green is, for example, twice as many as either one of the other picture elements.
