PROBLEM TO BE SOLVED: To provide a device capable of full-color display with a simple constitution. SOLUTION: One display dot consists of two adjacent picture elements in a double refraction control type liquid crystal display element 1 which has the display color changed in the range of a low applied voltage and has the gradation changed in achromatic color in the range of a high applied voltage. A driving circuit 2 converts picture data to color data and gradation data and applies a voltage corresponding to color data to one of two adjacent picture elements of the double refraction control type liquid crystal display element 1 and applies a voltage corresponding to gradation data to the other. The display color and the display gradation of two adjacent picture elements are visually synthesized to recognize a color gradation picture. |
