  • Patent number: 8570466
    Abstract: There are provided a thin film transistor substrate for transflective liquid crystal display device (LCD) and a manufacturing method thereof, which can reduce manufacturing cost and simplifying manufacturing processes. In the method, a thin film transistor is formed on a reflection region of a device substrate defined by the reflection region and a transmission region. A passivation layer is formed on the thin film transistor so as to expose a drain electrode of the thin film transistor and to cover the thin film transistor. A pixel electrode is formed on the transmission and reflection regions. The pixel electrode has a structure of a first pixel electrode electrically connected to the drain electrode and a second pixel electrode formed to have an embossed pattern on the first pixel electrode. A reflective layer is formed on the second electrode pixel having the embossed pattern on the reflection region.

  • Publication number: 20060125986
    Abstract: An array substrate includes a transparent substrate, a switching device, an insulation layer, a pixel electrode, a reflective plate and an inner polarization layer. The transparent substrate has a reflective region and a transmissive region. The switching device is formed in the reflective region. The insulation layer is formed on the transparent substrate to cover the switching device. The insulation layer has a contact hole that exposes a portion of a drain electrode of the switching device. The pixel electrode is electrically connected to the drain electrode of the switching device through the contact hole. The reflective plate is electrically connected to the pixel electrode and is disposed at the reflective region. The inner polarization layer covers the reflective plate. Thus the white luminance and the contrast ratio of an LCD apparatus having the above array substrate are enhanced.
