[0058] FIG. 7 is a cross-sectional view of a liquid crystal display panel according to yet another embodiment of the present invention. Please refer to FIG. 7 , this embodiment is similar to the above-mentioned first embodiment, the difference is that the retaining wall pattern 264 formed therein can be a structure composed of a lower layer 266 and an upper layer 268 . The steps of making this liquid crystal display panel 200" are to form the lower layer 266 of the wall pattern 264 at the same time when the channel layer 224 is formed on the insulating layer 240 above the grid 222 after the insulating layer 240 is formed. Therefore, the material of the lower layer 266 can be The same material as the channel layer 224. Then, when the source electrode 226 and the drain electrode 228 are formed on the channel layer 224, the upper layer 268 of the wall pattern 264 is formed simultaneously. Therefore, the material of the upper layer 268 can be the same as that of the source electrod...

Abstract

This invention discloses a sort of liquid crystal panel, and it consists of the first baseboard, several scanning beam, several data wire, an insulated layer, several thin film transistor, several picture element pole, several barricade pattern, a second baseboard, a liquid crystal layer, and several columnar gap matter. The scanning beam and the data wire are fixed in the first baseboard, and the insulated layer is fixed between the scanning beam and the data wire. The thin film transistor consists of a grid, a channel layer, a power pole, and a leakage pole, it is fixed in the first baseboard, and the grid connects with the scanning beam, the power pole connects with the data wire, and the leakage connects with the picture element electric pole. The barricade locates in the insulated layer, and its material is selected from that it is one of the power pole, leakage, and the channel layer. The second baseboard is fixed in the reverse of the first baseboard, the liquid crystal layer and the columnar gap matter locate between the first baseboard and the second baseboard, and the one port of the columnar gap matter is fixed in the bosom of the barricade pattern.

Description

technical field [0001] The present invention relates to a display panel and a manufacturing method thereof, and particularly relates to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] The multimedia technology in today's society is quite developed, most of which benefit from the progress of semiconductor elements or display devices. As far as displays are concerned, liquid crystal displays with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the mainstream of the market. [0003] A liquid crystal display panel is generally composed of two substrates and a liquid crystal layer sandwiched between the two substrates. In order to maintain the height of the gap between the two substrates, many spacers are usually arranged between the two substrates. However, since the traditional spacer is simply pushed between the two substrates...
