Abstract
A liquid crystal display includes a first liquid crystal panel and a second liquid crystal panel stacked on each other; and polarizers provided to the panels, together with a polarizer of an adjacent panel, arranged to define a crossed Nicols. When the first liquid crystal panel produces a display from a first display signal, the second liquid crystal panel produces a display from a second display signal obtained from the first display signal. Between a framework and drivers provided to the first liquid crystal panel and the second liquid crystal panel, heat conducting members are arranged to transfer heat from the drivers to the framework so as to improve luminance when two liquid crystal panels are stacked and achieve high display quality.
