Abstract: 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.
