Patent number: 9436024Abstract: To acquire a fine viewing angle property from oblique view fields in a lateral electric field type liquid crystal display device having liquid crystal initial alignment directions in two orthogonal directions. The absorption axis of the incident-side polarization plate and the absorption axis of the exit-side polarization plate are orthogonal to each other in both of the region I and the region II, and the liquid crystal layer, the in-cell retarder as an optical compensation layer, the A-plate, and the C-plate sandwiched therebetween are in parallel to either one of the absorption axes or orthogonal to the substrates. Therefore, the transmittance can be suppressed to be low and a fine black display can be acquired even when the display surface is viewed from the oblique view fields.Type: GrantFiled: March 1, 2013Date of Patent: September 6, 2016Assignee: NLT TECHNOLOGIES, LTDInventors: Shinichi Nishida, Hidenori Ikeno, Hideki Ito, Mitsuhiro Sugimoto

Publication number: 20160103381Abstract: Provided is to a display element capable of displaying an image on both sides thereof. In the display element, display operation is not constantly performed on both sides, and the display operation is, as necessary, switched to displaying only on one side without lowering the efficiency of a backlight or other light emitting bodies. The structure is made such that a planar light emitting body capable of emitting light in directions of both faces is sandwiched between two light control elements capable of electrically switching, from outside, between a light reflection state and a light transmission state. In such a structure, the faces of the light control elements serving as light reflection surfaces in the light reflection state face the planar light emitting body, and the planar light emitting body and the light control elements are further sandwiched between two liquid crystal elements.Type: ApplicationFiled: October 9, 2015Publication date: April 14, 2016Inventor: Hidenori IKENO
