Patent number: 10012863Abstract: A liquid crystal display panel for displaying images in an active area includes a first substrate having a pair of first short ends and first long ends. A second substrate faces the first substrate so as to hold a liquid crystal layer therebetween. A first polarization plate is arranged on an outside surface of the first substrate. The first polarization plate has a pair of second short ends longer than the first short ends, a pair of second long ends, and a first absorption axis. The angle a1 made by the first absorption axis with respect to the second short ends is smaller than an angle b1 made by the first absorption axis with respect to the second long ends. A second polarization plate is arranged on an outside surface of the second substrate and has a second absorption axis.Type: GrantFiled: June 15, 2017Date of Patent: July 3, 2018Assignee: Japan Display Inc.Inventors: Kayoko Miyazaki, Tatsuaki Kuji, Keiji Tago
