Abstract: A single liquid-crystal display can be used to be either of direct-vision or projection type, if required. Separate display devices for monitor and OHP are not required. Further, power consumption can be reduced, with the service life of the display being prolonged to improve economy.The liquid-crystal display includes a display housing which receives a liquid-crystal panel, a driver circuit unit and a cooling fan, the display housing being detachably mountable in a back light stand. When the display housing is mounted or dismounted in the back light stand, the fan and back light can automatically be turned on or off to reduce the power consumption. The liquid-crystal panel can be prevented from being degraded by cooling it by way of the fan.

Abstract: In a display housing, first and Second liquid-crystal panels are disposed in parallel with each other, and a fluorescent lamp is positioned beside both ends of a gap between these panels. Thus, when used for a transmission type display, e.g. an OHP, the first liquid-crystal panel for light shutter is set in a transmission condition to transmit light from a light source for the OHP or the like and to irradiate the second liquid-crystal panel for displaying an image, thereby projecting the image in a magnified size onto a screen or the like. When used for a direct-vision type display, e.g. a monitor for a personal computer or the like, the first liquid-crystal panel is set in a shading condition to effect diffuse reflection of light from the fluorescent lamp by the first liquid-crystal panel and to irradiate the second liquid-crystal panel, thereby providing a direct-vision image.
