Abstract
The invention relates to a TFT-LCD array substrate and a method for producing the same. The array substrate comprises a grid line, a data wire, a pixel electrode and a film transistor which are formed on the substrate, wherein, a grid pattern which can convert the natural light into the linearly polarized light and make the pixel electrode serve as a built-in polaroid sheet at the same time is formed on the pixel electrode. The method for producing the array substrate comprises the following steps that: a gate electrode and a grid line pattern are formed on the substrate; a grid insulating layer, a semiconductor layer and a doping semiconductor layer are sedimentated continuously; the semiconductor layer pattern and the doping semiconductor layer pattern are formed on the upper part of the gate electrode; source electrode, drain electrode and pixel electrode patterns are formed; moreover, the grid pattern which can convert the natural light into the linearly polarized light and make the pixel electrode serve as a built-in polaroid sheet at the same time is formed on the pixel electrode. The TFT-LCD array substrate and the method for producing the same do not need to stick an absorbing polaroid sheet on the array substrate at the back of a box, thereby lowering the production cost, reducing the thickness of the TFT-LCD and improving the energy utilization efficiency of a liquidcrystal display.
Description
technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a thin film transistor liquid crystal display array substrate and a manufacturing method thereof. Background technique [0002] With the rapid development of flat panel display technology, flat panel display devices have gradually replaced traditional CRT displays due to their advantages such as low power consumption and thinness, and have quickly entered people's daily lives. Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is accepted by consumers due to its long life, low power consumption and no radiation, and is widely used in people's life and production. However, seeking a liquid crystal display with low production cost, low power consumption, and thinner has always been the goal pursued by people. [0003] The main structure of the TFT-LCD includes an array substrate and a color filter substrate that are bo...
