Abstract

A color correction filter that while inhibiting any drop of luminance of image display apparatus, removes intermediate color light to thereby attain an enhancement of color tone expression of the image display apparatus, and that excels in durability. The color correction filter is color correction filter (10) characterized in that it has color correction layer (11) and two protective layers (12), the color correction layer (11) containing a J-aggregate of dye, the dye being at least one dye selected from the group consisting of cyanine, merocyanine, squarylium and porphyrin, and that the color correction layer has a half-value width of maximum absorption peak ranging from 5 to 30 nm, and that the two protective layers (12) are provided on both major surfaces of the color correction layer (11), respectively.

Description

technical field

[0001] The invention relates to a color complementary color filter, an image display device and a liquid crystal display device. Background technique

[0002] In recent years, a liquid crystal display device that forms an image by controlling light emitted by a light source device such as a cold cathode tube or a light emitting diode (LED) through a liquid crystal panel has been developed and put into practical use. In the liquid crystal display device, in order to uniformly distribute the light from the light source device over the entire display surface, the light guide plate overlaps the liquid crystal panel in parallel and is arranged on an optical path connected to the light source device. The light source device is disposed beside the light guide plate, or on the opposite side of the light guide plate to the liquid crystal panel.
