Abstract

PURPOSE: To eliminate the need for color filters by changing over the light emission colors of a back light having ≥1 emission colors by time sharing and setting the liquid crystal in a prescribed position at a transmission mode according to the timing of said change over, thereby making color display.
CONSTITUTION: This device has a liquid crystal panel 11 and electroluminescence (EL) as the back light. The EL is constituted of EL 12 which emits red light, EL 13 which emits green light and EL 14 which emits blue light. Power supplies PS1WPS3 and switches SW1WSW3 are connected to the EL having 3 kinds of such emission colors. On the other hand, the liquid crystal panel 11 is disposed with scanning electrodes S1WS3 and data electrodes D1WD4 in matrix and is provided with drivers for impressing voltages to the respective electrodes. The color display is thereby executed in one cell of the liquid crystal and the need for the color filters is eliminated.
