Abstract
A reflection type color liquid crystal display device including a liquid crystal cell to be controlled by a field sequential system and a reflection device disposed on the back side of the liquid crystal cell. In the reflection device, is a belt-like reflection sheet having reflection regions for reflecting lights of three colors R, G and B formed thereon. The reflection sheet is driven by a driver. A semi-transparent and semi-reflection type color liquid crystal display device includes a liquid crystal cell and a semi-transparent and semi-reflection device disposed on the back side of the liquid crystal cell. In the semi-transparent and semi-reflection device is a belt-like semi-transparent and semi-reflection film and a light source therein. The semi-transparent and semi-reflection film is driven by a driver.
