  • Patent number: 8629949
    Abstract: A liquid crystal display and a method of forming the same are disclosed. The method of forming the liquid crystal display comprises: forming a gate electrode and a common electrode on a substrate; forming a gate dielectric, which covers the gate electrode and the common electrode, on the substrate; forming a channel layer, which covers the gate electrode, on the gate dielectric; forming a source electrode and a drain electrode which expose a portion of the channel layer; forming an organic layer, which contacts the exposed portion of the channel layer, on the source electrode and the drain electrode; patterning the organic layer contacting the channel layer so as to form an organic layer pattern comprising a first opening which exposes the channel layer; and forming an inorganic insulation layer which covers the channel layer exposed by the first opening.

  • 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: 20090066861
    Abstract: A display with a built-in touch panel and a method of manufacturing the same are provided. The display includes: a first substrate and a second substrate, wherein the first substrate and the second substrate are disposed to face each other. A conductive spacer having a first end is positioned on the first or second substrate. A cell gap spacer is disposed between the first and second substrates and at least one subsidiary cell gap spacer having a first end is disposed on the first or second substrate and positioned adjacent to the cell gap spacer. The cell gap spacer is also disposed close to the conductive spacer, and the subsidiary cell gap spacer is disposed adjacent to the cell gap spacer. Additionally, a cell gap spacer is disposed in every unit pixel, and a subsidiary cell gap spacer is disposed adjacent to each cell gap spacer.

  • 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.
