Liquid crystal display (50, 55, 60, 90, 95) having a liquid crystal device (30) as a light switching element, and employing an electroluminescent (EL) element (40, 61, 80, 94) 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 (36, 66), sealed between a pair of light permeable substrates (32, 33, 63), and transparent pixel electrodes (38, 64) which are driven by electrical signals corresponding to image information supplied to the device. A pair of light polarizers (31, 35, 62, 68), aligned to each other, are disposed on the outer sides of the light permeable membranes. An EL backlight source (40, 61, 80, 94) is formed by sequentially stacking a first electrode (42, 73), a dielectric layer (44, 72), a phosphor layer of oxide phosphor material (45, 71), a transparent dielectric layer (43, 70), and a transparent second electric layer (41, 69) on a substrate (47, 74) to form a thick or thin film EL device structure, and light from the EL structure illuminates one side of the liquid crystal device.
