Document Type and Number:
WIPO Patent Application WO/2023/013652
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical-semiconductor-device sealing sheet that is suitable for manufacturing a self-emitting display device, e.g., a mini/micro-LED display device, that has a metal-wiring antireflection function, that has improved contrast, and that has a reduced color cast. An optical-semiconductor-device sealing sheet 10 according to the present invention includes a diffusion layer 1 and an antireflection layer 2. The total light transmittance T1 of the diffusion layer 1 and the total light transmittance T2 of the antireflection layer 2 satisfy T1 > T2, and the haze value H1 of the diffusion layer 1 and the haze value H2 of the antireflection layer 2 satisfy H1 > H2.
