Patent number: 10606103Abstract: A concave display including a first substrate, a second substrate, a display medium, a color filter layer, an optical film and an active device layer is provided. The second substrate is disposed opposite to the first substrate. The display medium is disposed between the first substrate and the second substrate. The color filter layer is disposed on the first substrate. The active device layer is disposed on the first substrate or the second substrate. The optical film is disposed on the first substrate. The optical film is further away from the display medium than the color filter. The optical film includes a base material and optical microstructures embedded in the base material, wherein a refractive index of each of the optical microstructures is smaller than a refractive index of the base material.Type: GrantFiled: September 11, 2017Date of Patent: March 31, 2020Assignee: GIANTPLUS TECHNOLOGY CO., LTDInventors: Chih-Teng Huang, Hsin-Yu Han, He-Guei Chen, Hsiao-Ching Shen
