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.
