20080303753 | Display apparatus - Provided is a display apparatus that includes a panel assembly which has a plurality of substrates and displays images, and a filter assembly which is formed in front of the panel assembly, has a base film, a refraction control film layer that is attached to at least a surface of the base film and has a refractive index different from that of the base film, and an optical absorption layer that is formed on an outer surface of the base film or the refraction control film layer to absorb refracted incident external light. The display apparatus can increase bright room contrast by absorbing incident external light by employing a film coated with a black group color on a front surface of a panel. Also, a direct attachable filter assembly is used to remove an interface between the substrate and the filter assembly. Thus, a double image problem caused by refraction of light at the interface is prevented. | 12-11-2008 |
