Patent number: 10050077Abstract: A device including a substrate and an imaging element layer having a plurality of imaging elements is provided, where the imaging element layer is located between the substrate and a wiring layer having a plurality of wiring lines (41), and wiring lines of the wiring layer are arranged in pixel regions (Z) configured to receive light having a wavelength less than a predetermined wavelength (B, G). Accordingly, by more uniformly distributing the wiring layer throughout, it is possible to reduce an unevenness that occurs at a polishing film. Moreover, because wiring lines are not disposed in pixel regions (Z) configured to receive light having a wavelength greater than the predetermined wavelength (R), irregularities may be reduced.Type: GrantFiled: July 22, 2014Date of Patent: August 14, 2018Assignee: Sony CorporationInventor: Tadahiro Hagita

Patent number: 7652739Abstract: A matrix-addressed type liquid crystal display apparatus having switching devices such as TFTs is provided, featuring that an increased effective voltage can be applied without causing hysteresis in V-T characteristics. Namely, by substantially increasing a value of an applicable voltage in excess of which a display defect starts to appear, a high numerical aperture and a high contrast ratio have been achieved at the same time. In the LCD apparatus of the present invention, a gap between adjacent reverse tilt domains each formed in a portion of a pixel which is arranged corresponding to an arbitrary pixel electrode becomes broader than a minimum gap between adjacent pixel electrodes corresponding thereto, or a thickness of a liquid crystal cell in the portion between adjacent reverse tilt domains is set thinner than a thickness of a liquid crystal cell in the portion of the pixel.Type: GrantFiled: October 30, 2006Date of Patent: January 26, 2010Assignee: Sony CorporationInventors: Hisanori Tsuboi, Fumiaki Abe, Katsuhide Uchino, Kazuhiro Noda, Hideshi Sugita, Tadahiro Hagita, Hiromi Fukumori, Syuichi Shima, Kikuo Kaise
