Optical member and display device
An optical member realizing suppressed occurrence of a light loss between a phosphor layer performing color conversion and itself, and a display device using the same is provided. The optical member includes a base member having two opposed surfaces, and a phosphor layer provided integrally with one surface of the base member and containing a phosphor that converts a color light to another color light.
1. A display device comprising:
a light source;
an optical member transmitting light emitted from the light source;
a display panel displaying an image by using the light passed through the optical member; and
a diffusion film, a lens film, and a reflection-type polarization film provided in order from the optical member between the optical member and the display panel,
wherein the optical member comprises:
a diffusion plate having two opposed surfaces,
a phosphor layer provided directly on one of the two opposed surfaces of the diffusion plate and containing a phosphor that converts a color light emitted from the light source to another color light, and
a protection layer provided on a surface of the phosphor layer opposite to the diffusion plate,
wherein the phosphor layer is made of cycloolefin resin and the protection layer is made of a material having gas barrier property.
