Abstract
A liquid crystal projection display apparatus is disclosed. The display apparatus includes a thermally addressed liquid crystal light valve including in the following order a transparent substrate, a first transparent conductive layer, a light absorbing layer, a light reflecting layer, a first liquid crystal alignment layer, a liquid crystal material, a second liquid crystal alignment layer, a second transparent conductive layer and a transparent substrate. At least one of the first and second transparent conductive layers is provided with a distributed resistance which causes heat due to the supply of current thereto to be evenly distributed.
