Publication number: 20160370597Abstract: Conventional optical elements cannot emit circularly polarized light beams obtained by beam separation in the same direction. An optical element includes a polarization splitter element configured to split incoming light into a first circularly polarized light beam and a second circularly polarized light beam that has different handedness than the first circularly polarized light beam, where the polarization splitter element is configured to reflect the first circularly polarized light beam and allow the second circularly polarized light beam to transmit, and a reflector element configured to reflect the first circularly polarized light beam that has been reflected by the polarization splitter element, to proceed in a direction in which the second circularly polarized light beam is allowed to transmit.Type: ApplicationFiled: September 5, 2016Publication date: December 22, 2016Inventors: Yuichi KAKUBARI, Kenichi WATABE

Patent number: 9158123Abstract: A light diffraction element comprising a transparent substrate and a first orientation layer that is formed on one surface of the substrate and includes anisotropic polymers and a first pattern of an orientation direction arranged periodically in a first direction along the primary plane of the substrate. The first pattern includes three or more small regions that are arranged in the first direction and in which the orientation direction of the polymers included in the first orientation layer are different from each other, and generates diffracted light as a result of interference between light passed respectively through the three or more small regions.Type: GrantFiled: September 20, 2013Date of Patent: October 13, 2015Assignee: ARISAWA MFG. CO., LTD.Inventors: Yuichi Kakubari, Yasuaki Umezawa, Kenichi Watabe

Patent number: 8194316Abstract: It is aimed to reduce the occurrence of crosstalk attributable to the thermal expansion/contraction of a retarder and an image display section, and the unevenness in color attributable to the uneven surfaces of the retarder and the image display section. It is also aimed to reduce the misalignment of the retarder with respect to the image display section. The exit surface of an image display section 130 and the entrance surface of a retarder 180 are adhered to each other by using an adhesion layer 300. Additionally, the left and right edges of the image display section 130 are adhered to the left and right edges of the retarder 180 by using adhesion regions 400. Here, the adhesion regions 400 have a higher glass transition temperature than the adhesion layer 300.Type: GrantFiled: April 1, 2008Date of Patent: June 5, 2012Assignee: Arisawa Mfg. Co., Ltd.Inventors: Yoshiyuki Tamura, Kei Fukaishi, Yuichi Kakubari, Hideki Ohshima
