Abstract

The present invention provides a liquid crystal display device in which a direction of an orientation axis of a liquid crystal is changed based on an electric field component in a direction different from a normal direction of a main surface of a substrate, and electronic equipment including the liquid crystal display device. , the liquid crystal display device includes: a transmissive part and a reflective part arranged on the substrate; wherein, the voltage applied to the liquid crystal in the transmissive part is different from the voltage applied to the liquid crystal in the reflective part. The liquid crystal display device of the present invention can be mass-produced with high yield, and can suppress image quality deterioration.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2007-026852 filed in the Japan Patent Office on Feb. 6, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a liquid crystal display device using a combination of reflective display and transmissive display, and electronic equipment including the liquid crystal display device. Background technique [0004] Liquid crystal display devices are widely used as display devices for various electronic devices by taking advantage of the characteristics of each liquid crystal display device being slim and consuming less power. [0005] For example, various electronic equipment using liquid crystal display devices are known, such as notebook personal computers, display devices for car navigation, personal digital assistants (PDAs), mobile phones, digital cameras, and ...
