Patent ID: 7233374

Claim:
A transflective array substrate for a liquid crystal display device, comprising: a substrate; a thin film transistor on the substrate, the thin film transistor including a gate electrode, a source electrode, a drain electrode, and an active layer, wherein the gate electrode is disposed between the active layer and the substrate, and wherein the thin film transistor includes a channel; a first passivation layer on the thin film transistor having a refractive index and an average thickness; a reflector on the first passivation layer, the reflector covering the channel and a portion of a pixel region, and the reflector having a reflectivity; a second passivation layer on the reflector; and a transparent electrode on the second passivation layer, the transparent electrode contacting the drain electrode of the thin film transistor, wherein the reflector has an opening over the drain electrode, the opening having a distance from the channel, the distance selected based on the refractive index, the average thickness, and the reflectivity, and the distance selected such that light incident on the opening is reflected off the drain electrode at least twice before reaching the channel, and wherein the reflector corresponds to the transparent electrode.
