Liquid crystal display devices having an electroluminescent backlight assembly

Abstract

Liquid crystal display having a liquid crystal device as a light switching element, and employing an electroluminescent (EL) element as the light source. A liquid crystal display according to the present invention has a liquid crystal device for controlling light transmission depending on image information, and a light source. The liquid crystal device includes a liquid crystal material layer, sealed between a pair of light permeable substrates, and transparent pixel electrodes which are driven by electrical signals corresponding to image information supplied to the device. A pair of light polarizers, aligned to each other, are disposed on the outer sides of the light permeable membranes. An EL backlight source is formed by sequentially stacking a first electrode, a dielectric layer, a phosphor layer, a transparent dielectric layer, and a transparent second electrode layer on a substrate to form a thick or thin film EL device structure, and light from the EL structure illuminates one side of the liquid crystal device.
