Abstract

The present invention provides a liquid crystal display device, an electric equipment using the liquid display device and the method for making the liquid crystal display element. As the liquid crystal display device comprises a phase difference layer which causes the liquid crystal molecules compositely oriented and the device has the characters of excellent visual angle, high contrast and excellent display character. The liquid crystal display device (1a) of the electric field double-refraction mode is combined with the following components: a liquid crystal unit which is formed by clampingthe liquid crystal layer LC between a pair of transparent substrates (11-21); a composite phase difference layer (23) which orients the liquid crystal molecules compositely, wherein, the formed-film of the composite phase difference layer (23) forms at the side of the liquid crystal layer LC of the transparent substrate (21) at the side of the opposite substrate (20) which is one of the pair of the transparent substrates (11, 21).

Description

technical field [0001] The present invention relates to an Electrically Controlled Birefringence (ECB) mode liquid crystal display element having a retardation layer for hybrid alignment of liquid crystal molecules, an electronic device using the liquid crystal display element, and a method for manufacturing the liquid crystal display element. Background technique [0002] Conventionally, as a general drive mode for liquid crystal display elements used in personal computers, the twisted nematic mode, which has high transmittance and can be displayed only by combining with a polarizer, has been applied. Among them, as the demand for display elements for mobile electronic devices such as personal digital assistants (PDAs) and mobile phones has increased rapidly, a liquid crystal display element that consumes less power and has higher visibility outdoors than transmissive liquid crystal display elements is being developed. semi-transmissive liquid crystal display element.
