Publication number: 20260044040Abstract: According to one embodiment, a display device includes a prism sheet configured to split illumination light from a light source into transmitted light and refracted light, a liquid crystal panel illuminated by transmitted light and refracted light, a diffusion sheet between the prism sheet and the liquid crystal panel, a first polarizer between the diffusion sheet and the liquid crystal panel, and a second polarizer. A first normal of an emission surface of the light source and a second normal of the liquid crystal panel intersect at an acute angle. The first polarizer has a first transmission axis and is configured to transmit p-polarized light and absorb s-polarized light, and the second polarizer has a second transmission axis orthogonal to the first transmission axis.Type: ApplicationFiled: August 6, 2025Publication date: February 12, 2026Applicant: Japan Display Inc.Inventors: Daisuke SUMI, Shota HASEGAWA

Patent number: 9256090Abstract: According to an aspect, a display device includes a first substrate, a second substrate, and light shielding layer. The first substrate is a plate-like member and is provided with a switching element for each of pixels arranged in a matrix and a wiring coupled to the switching element. The second substrate is a plate-like member facing the first substrate and having a smaller thickness than the thickness of the first substrate. The second substrate has an outer edge that faces a portion of the first substrate to which the wiring is not led out and that is positioned inside an outer edge of the first substrate when viewed from a direction orthogonal to a substrate surface of the first substrate.Type: GrantFiled: March 11, 2014Date of Patent: February 9, 2016Assignee: Japan Display Inc.Inventors: Takuya Kiyama, Daisuke Sumi

Patent number: 7278326Abstract: A pressure sensor comprising a plurality of sensor parts arranged in matrix. A first electrode being connected with first wiring and a second electrode being connected with second wiring are disposed oppositely through a cavity part in the sensor part. The second electrode bends to the first electrode side in response to a pressure from a specimen and touches the first electrode upon application of a pressure of a specified level or above. When the specimen is pressed against a pressure detecting region, both electrodes touch each other at a sensor part corresponding to a protrusions of the specimen and are separated at a sensor part corresponding to a recess. When a scanning signal is fed from a scanning circuit to one wiring and presence of a signal flowing through the second wiring is detected by a sensing circuit, a pressure being applied to each sensor part can be detected.Type: GrantFiled: March 27, 2003Date of Patent: October 9, 2007Assignees: Sanyo Electric Co., Ltd., Tottori Sanyo Electric Co., LtdInventors: Chiaki Kobayashi, Daisuke Sumi, Hiroshi Inamura, Togo Morifuji, Koji Yoshida, Masaki Endo, Sayaka Hiura, Takao Yamauchi, Syunsuke Yamaura, Kaoru Taketa, Kimihiko Nagami
