Abstract
A color conversion filter substrate includes a transparent support substrate, at least one color conversion filter layer formed of a resin film containing a fluorescence colorant with a thickness of at least 5 μm and arranged on the support substrate in a desired pattern, and a transparent gas-barrier layer formed in a flat film for covering the color conversion layer. The gasbarrier layer has a water-vapor permeability of 1.0 g/m2·24 hr or less, and a portion covering the color conversion filter layer with a thickness tPL expressed by the following equation, 0<tPL<0.1 W wherein W is a minimum width of a pixel.
Claims5
A color conversion filter substrate, comprising:
- a transparent support substrate,
- at least one color conversion filter layer formed on the support substrate in a pattern and formed of a resin film containing a fluorescence colorant, and
- a gas-barrier layer formed of a transparent film for covering in a flat form the at least one color conversion layer and a surface of the transparent support substrate on which the color conversion layer is formed, said gas-barrier layer having a water-vapor permeability of equal to or less than 1.0 g/m2·24 hr and having a portion on the color conversion filter layer with a thickness tPL defined by:
- 0<tPL<0.1 W
- wherein W is a minimum width of the at least one color conversion filter layer
