摘要： A liquid crystal display device having a back side light source, which can perform displays of both a transmissive type and a reflective type, employs interference filters formed with a multilayer film 18, 19 and 20 as color filters to be used for color display. The back side light source is switched off in use as a reflective type display. The display in the liquid crystal display device can be inverted to a negative. The normal direction of the multilayer film of the interference filter may differ from the normal direction of a substrate.

A voltage is applied to a liquid crystal layer until display area in the liquid crystal layer is transformed to the displayable alignment. After the completion of the transition, a backlight is switched on to shift to a display-driving mode. In order to complete the transition in a short time, voltage pulse under the conditions (such as a frequency and a voltage value) determined in accordance with a temperature of a liquid crystal panel is applied to the liquid crystal layer.
