Title:
半導体装置
Document Type and Number:
Japanese Patent JP5211259
Kind Code:
B2
Abstract:
It is an object to provide a liquid crystal display device which can recognize image display even in the dim surrounding environment of the liquid crystal display device. It is another object to provide a liquid crystal display device which can perform image display in both modes: a reflective mode in which external light is used as an illumination light source; and a transmissive mode in which a backlight is used. A plurality pairs of a pixel in which incident light through a liquid crystal layer is reflected and a light-transmitting pixel are provided; therefore, display image can be performed in both modes: the reflective mode in which external light is used as an illumination light source; and the transmissive mode in which a backlight is used. Further, each reflective pixel and light-transmitting pixel may be connected to an independent signal driver circuit.
