Publication number: 20200409219Abstract: A display apparatus includes a light source, a diffusion plate, a display panel, and a scattering member. The light source emits light. The diffusion plate diffuses the light emitted from the light source. The display panel has a display area. The diffusion plate and the display panel are spaced away. The scattering member is located between the display panel and the diffusion plate with the scattering member located nearer the diffusion plate than the display panel. The diffusion plate has a first incidence surface and a first exit surface. The first incidence surface allows the light emitted from the light source to be incident thereon. The first exit surface is smaller than the display area. The diffusion plate allows the light entered from the first incidence surface to exit from the first exit surface with the light diffused. The scattering member allows the light exited from the first exit surface to pass therethrough with the light passing therethrough scattered.Type: ApplicationFiled: June 2, 2020Publication date: December 31, 2020Inventors: DAISUKE TERAGAWA, TOMOHIRO ASAMIZU, NORIAKI MIYOSHI
