Abstract
A liquid crystal display ('LCD') includes forming only a λ/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 λ/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 λ/2 and λ/4 plates. In addition, in an ECB mode backlit LCD, transmittance, contrast ratio, and viewing angles can be enhanced by attaching both the λ/4 or λ/2 plate and allowing the absorption axis of the polarizer and the slow axis of the λ/4 and λ/2 plates to have predetermined angle relationships.
