Patent Searching and Data

Document Type and Number:
Japanese Patent JP2002524772
Kind Code:
A photoluminescent liquid-crystal display includes a liquid crystal (31) sandwiched between two transparent substrates (1, 21) for modulating input light, control electrodes (13, 23) for controlling the liquid crystal, and display output means incorporating a photoluminescent material (3) such as a phosphor for producing a visible image from the input light modulated by the liquid crystal. The phosphor is at the inner face (16) of the front substrate (1) but is sepraated from the liquid-crystal by a thin transparent auxiliary substrate (7) having a thickness of less than about 300 mum. This allows the phosphors to be close to the liquid-crystal layer (31), minimising crosstalk, without interfering with the electro-optic properties of the device.
