Patent number: 9454050Abstract: LCD device includes two substrates, a first and second color filters, two liquid crystal layers. The first color filters are formed on portions of the second substrate corresponding to border area The second color filters are formed on portions of the second substrate corresponding to the display area except the border area. A first liquid crystal layer between the first and the second substrate is comprised in border area, and a zero electric field is formed on the first liquid crystal layer so as to completely transmit light incident into the first liquid crystal layer therethrough. A borderline having various colors can be displayed by forming various patterns of color filters having various colors on portions of the second substrate corresponding to the border area under normally white mode, thereby producing picture frame effect while images are displayed on the screen.Type: GrantFiled: January 30, 2015Date of Patent: September 27, 2016Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Yong-Ho Yang, Dong-Ho Lee, Soong-Yong Joo
