An LCD(Liquid Crystal Display) is provided to form a light control pattern with a constant angle to a side of a light guide panel, thereby minimizing the generation of a moire pattern. A reflection member is located at the lower portion of an LCD panel. A light guide panel has a transparent sheet and plural light control patterns(132) formed on the transparent sheet and is located at the upper portion of the LCD panel. A light supply member is located at a side of the light guide panel and supplies the light beam to the light guide panel. The light control pattern has the first inclination surface(132a) extended toward the first direction. The second inclination surface(132b) is extended toward the second direction. A cross-section with a triangle shape is defined by the upper surface of the transparent sheet. The first inclination angle formed by the first inclination surface and the upper surface of the transparent sheet is smaller than that formed by the second inclination surface and the upper surface of the transparent sheet.
