Embodiment Construction

[0068] In the known thin film transistors, one or more insulating layers must be arranged to electrically insulate the gate from the source, drain and channel layers. Since there are various insulating materials that can convert light and filter light, the present invention proposes to use insulating materials that can make light appear in different colors to fabricate the insulating film layer of the thin film transistor and the pixel structure. In this way, the light can present a specific color after passing through the thin film transistor, pixel structure and related elements or display device of the present invention.

[0069] FIG. 1 shows a thin film transistor of an embodiment of the present invention. Referring to FIG. 1 , the thin film transistor 100 is disposed on a substrate 110 . The thin film transistor 100 includes a gate 120 , a semiconductor layer 130 , a gate insulating layer 140 , and a source 152 and a drain 154 . The gate insulation layer 140 is located ...

Abstract

The present invention provides a thin film transistor, a pixel structure and a liquid crystal display panel. Wherein, the thin film transistor is arranged on a substrate and comprises a grid, a semiconductor layer, a grid insulating layer, a source electrode and a drain electrode. The grid insulating layer is positioned between the grid and the semiconductor layer. Rays show specific color after passing through the grid insulating layer. In addition, the source electrode and the drain electrode are arranged on the semiconductor layer. For the liquid crystal display panel, it is unnecessary to additionally arrange a color filter array to display multicolor images, thus simplifying liquid crystal display panel production technique and ensuring lower production cost. Besides, the present invention adopts insulating materials with functions of ray filter or ray color conversion as material of the insulating film in the thin film transistor. Therefore, rays show specific color after passing through the insulating film of the thin film transistor.

Description

technical field [0001] The present invention relates to a thin film transistor, a pixel structure and a liquid crystal display panel using the thin film transistor and the pixel structure, and in particular to a thin film transistor with light color conversion or light filtering function, the pixel structure and the application of the thin film transistor and the pixel structure A liquid crystal display panel with a pixel structure. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display, FPD) has been vigorously developed. Among them, the liquid crystal display is based on its low voltage operation, no radiation scattering, light weight and small size. Gradually replace the traditional cathode ray tube display and become the mainstream of display products in recent years. [0003] Generally speaking, a liquid crystal display panel in a liquid crystal ...
