A method for manufacturing a lower substrate of a liquid crystal display device is disclosed. The method comprises the steps of: (a) forming a patterned first metal layer, a first insulating layer, a patterned second metal layer and a second insulating layer on a substrate in sequence; (b) coating a transparent electrode layer and a negative photo resist layer on the second insulating layer; (c) irradiating the photo resist layer from the second surface of the substrate; (d) irradiating the photo resist layer from the first surface of the substrate, wherein part of the photo resist layer superposed over the second metal layer is covered by a mask; and (e) removing un-reacted photo resist and patterning the transparent electrode.

Method for manufacturing lower substrate of liquid crystal display device

A liquid crystal display includes an upper substrate, a lower substrate and a liquid crystal layer interposed between the upper substrate and the lower substrate. The lower substrate includes a pixel array divided into a plurality of columns of pixel areas and a plurality of rows of pixel areas. Each pixel area includes a upper sub-pixel electrode, a lower sub-pixel electrode insulated to the upper sub-pixel electrode and a TFT switch electrically connected to the lower sub-pixel electrode. The upper sub-pixel electrode is electrically connected to a lower sub-pixel electrode of a previous column, and the lower sub-pixel electrode is electrically connected to a upper sub-pixel electrode of a next column.

Liquid crystal display including neighboring sub-pixel electrodes with opposite polarities in the same pixel

A liquid crystal display has a pixel array including first and second pixel electrodes. Each of the first pixel electrodes is divided into at least two first sub-pixel electrodes in two pixel areas sharing a corner or an edge. Similarly, each of the second pixel electrodes is divided into at least two second sub-pixel electrodes in two pixel areas sharing a corner or an edge. The polarities of the first and the second electrodes are opposite. The first and the second pixel electrodes are arranged alternatively to allow at least one first sub-pixel electrode and at least a second sub-pixel electrode to be located in each pixel area.

A method of fabricating a pixel structure is disclosed. A substrate having a color filter layer thereon and a leveling layer further covers the color filter layer is provided. A first metal layer is formed over the leveling layer. The first metal layer is patterned to define a source/drain. A channel material layer, a gate insulating layer and a second metal layer are formed over the substrate to cover the source/drain. The second metal layer, the gate insulating layer and the channel material layer are patterned to define a gate and a channel layer. A passivation layer is formed over the substrate to cover the gate. The passivation layer is patterned to expose a portion of the drain. A transparent conductive layer is formed over the substrate, and is electrically connected to the exposed drain. Thereafter, the transparent conductive layer is patterned to form a pixel electrode.

Fabricating method of a pixel structure

Transparent regions are allocated on the color filter regions to promote luminance of LCD devices. Shielding regions are allocated on the pixels regions of TFT substrate corresponding to the transparent regions to promote chromatics. These two designs can be adapted to both display devices for laptop computers with high luminance requirement and desktop computers with pure chromatics requirement.

General-purposed LCD panel

Pixel structure, and thin film transistor

A method of fabricating a thin film transistor array is provided. A first patterned conductive layer that distributes over an area range exceeding the designated display region is formed over a substrate. A first dielectric layer is formed over the substrate, wherein the first dielectric layer has the thickness getting smaller toward the edge, so that the first patterned conductive layer outside the designated display region is exposed. A second patterned conductive layer is formed over the first dielectric layer. The second patterned conductive layer and the exposed first patterned conductive layer are electrically connected. A second dielectric layer having a plurality of contact openings therein is formed over the substrate. A plurality of pixel electrodes is formed over the second dielectric layer such that the pixel electrode and the second patterned conductive layer are electrically connected through the contact openings. Finally, various layers outside the designated display regions are removed.

Method of fabricating thin film transistor array

A wiring structure comprising a plurality of conductive wires coupled between a plurality of pixel terminals and a plurality of signal terminals of a flat panel display. Each conductive wire has a first portion of a first material with a first impedance and a second portion of a second material with a second impedance. Therefore, each conductive wire has the same impedance, thus enabling synchronous signal transmission and avoiding unstable display quality due to impedance disparity and asynchronous signals.
