Abstract: The invention relates to a transflective liquid crystal display device that has a high contrast ratio. The transflective liquid crystal panel includes a homogeneous liquid crystal such that the transflective liquid crystal display device will have an optical retardation when the voltage is applied. Therefore, in order to compensate the optical retardation caused by this liquid crystal, a thickness of the liquid crystal layer is adjusted. Moreover, a thickness of the retardation film is also adjusted. Accordingly, the complete dark state and the high contrast ratio are achieved in the liquid crystal display.

Abstract translation: 本发明涉及一种具有高对比度的半透射型液晶显示装置。 半透射型液晶面板包括均匀的液晶，使得透射型液晶显示装置在施加电压时将具有光学延迟。 因此，为了补偿由该液晶引起的光学延迟，调整液晶层的厚度。 此外，还调整相位差膜的厚度。 因此，在液晶显示器中实现完全黑暗状态和高对比度。
