Title:
ANTIREFLECTION FILM-EQUIPPED TRANSPARENT SUBSTRATE AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/195497
Kind Code:
A1
Abstract:
The present invention pertains to an antireflection film-equipped transparent substrate which is formed from: a transparent substrate which has two main surfaces; and a diffusion layer and an antireflection film which are disposed on one main surface of the transparent substrate in said order from the transparent substrate side. In the case of this substrate, when reflection on the other main surface of the transparent substrate is eliminated and light is incident on the one main surface at an incidence angle of 45˚ from a light source, then at D65 light source, a* and b* of diffused reflected light at respective angles of 15˚, 25˚, and 45˚ with respect to regular reflected light satisfy expressions (1) to (3) given below.
(1) -8 ≤ a* ≤ 1 (2) -2 ≤ b* ≤ 6 (3) b* ≤ -1 x a* - 1
