Abstract

A Liquid Crystal Display (LCD), a backlight used for the LCD and a method for producing the LCD and the backlight are provided which are capable of inhibiting an increase in component counts and in assembling processes and of reducing them, thereby achieving low costs. A display image is obtained by arranging a backlight section being able to perform scanning as a single unit in a manner that it positionally matches a liquid crystal displaying section. The backlight section is provided with a plurality of scanning electrodes and light emitting layers each providing a different luminescent color, and being spatially separated from each other on a principal face of the backlight and scanning is performed on a plurality of light emitting layers providing a different luminescent color.

Description

[0001] 1. Field of the Invention

[0002] The present invention relates to a liquid crystal display device, a backlight used for a same display device, a method for driving a same backlight and a method for manufacturing a same backlight.

[0003] The present application claims priorities of Japanese Patent Application No. 2001-324873 filed on Oct. 23, 2001, which are hereby incorporated by reference.

[0004] 2. Description of the Related Art

[0005] In recent years, a remarkable improvement in performance of a liquid crystal display device (hereinafter being referred to an "LCD") is yielded and also a remarkable progress in making its screen larger is made. The LCD having a large screen is used as a monitor for a personal computer or a like. Development work of a liquid crystal television by expanding technology of the LCD with a large screen is actively proceeding.

[0006] In such an application to the television, an improvement in performance of displaying a moving picture in an LCD is stron...
