Abstract
The invention relates to a liquid crystal display device and a projection TV using same. The liquid crystal display device has microfine conductive bumps formed on terminals of a liquid crystal display panel, and a conductive joint layer formed on each conductive bump. The display panel is connected to wiring leads formed on a substrate provided thereon an IC drive circuit. The projection TV employs a liquid crystal display device in which three liquid crystal display panels corresponding to three colors, red, green, and blue, are mounted on a single substrate. Light beams are made incident on the respective panels, and light beams transmitted through or reflected from specified pixels are projected on a screen to form an image.
