A second passivation layer made of a second material is deposited on the first passivation layer. The second passivation layer is patterned, thereby forming a first drain contact hole exposing the first passivation layer over the drain electrode. A reflector is formed on the second passivation layer, the reflector having a first transmissive hole The first passivation layer is patterned thereby forming a second drain contact hole exposing the drain electrode. The second drain contact hole corresponds to the first drain contact hole.

摘要： The invention relates to an array substrate for use in a transflective liquid crystal display device that has a high contrast ratio. The array substrate includes a first light-shielding pattern on a substrate, which is made of the same material as a gate electrode. The array substrate further includes a second light-shielding pattern that is made of the same material as an active layer in the same process step. These first and second light-shielding patterns are disposed in a border portion between the transmissive portion and the reflective portion, where the liquid crystal molecules are misaligned and the light is distorted. The first and second light-shielding pattern prevents the light leakage occurring in the border region between the transmissive portion and the reflective portion, thereby increasing the contrast ratio of the transflective LCD device.
