Publication number: 20220004059Abstract: A display according to an embodiment of the disclosure includes a light-emitting device and a display panel unit. The light-emitting device includes a light guide plate, a light source, a reflecting plate, and a dot pattern. The light guide plate has a light-outputting surface including a plurality of band-shaped projections extending in a direction orthogonal to the light-entering end surface. The light source is disposed along the light-entering end surface. The reflecting plate is disposed to face the rear surface of the light guide plate. The dot pattern fixes the light guide plate and the reflecting plate to each other and serves as a light scatterer. The display panel unit includes a display panel, an optical sheet, and a fixing layer. The fixing layer adheres or sticks the display panel and the optical sheet to each other and serves as a light diffuser.Type: ApplicationFiled: September 15, 2021Publication date: January 6, 2022Applicant: Saturn Licensing LLCInventors: Takeshi Yamamoto, Kouki Miura, Tomoyuki Yoshimatsu
