Abstract

PURPOSE:To display a beautiful color picture even at the dark place by fitting a sheet-like lamp emitted by electroluminescence under a semi-transparent reflecting plate arranged under a liquid crystal panel. CONSTITUTION:A sheet-like lamp emitted by electroluminescence, which is the same size as that of a liquid crystal panel or slightly larger than that, is fitted under a semi-transparent reflecting plate 11 arranged under the liquid crystal panel and a switch is attached to the external. Extremely high contrast can be obtained without any operation at a bright place and, even if surroundings are dark, transmissive beautiful color pictures are displayed by turning on the switch.
