  • Patent number: 8023073
    Abstract: A liquid crystal display (“LCD”) includes forming only a ?/4 plate between a polarizer and a display panel and setting a direction of an absorption axis of the polarizer and a slow axis of the ?/4 plate, so that the LCD can have a smaller thickness and its fabrication cost can be reduced while having better or the same characteristics than an LCD using both ?/2 and ?/4 plates. In addition, in an ECB mode backlit LCD, transmittance, contrast ratio, and viewing angles can be enhanced by attaching both the ?/4 or ?/2 plate and allowing the absorption axis of the polarizer and the slow axis of the ?/4 and ?/2 plates to have predetermined angle relationships.
