Problems solved by technology

[0006] However, the above-mentioned known LCDs have many disadvantages
For example, when the Cs line 120 breaks 190, it will cause horizontal bright lines or dark lines and affect the display quality, so the panel needs to be scrapped
Also, since the laterally extending Cs lines 120 are opaque, the aperture ratio of the pixel will be reduced.
In addition, cross talk may occur at the intersection of the Cs line 120 and the source line 150, thereby affecting the display quality.

Abstract

It is a LCD device and its process method, which comprises the following steps: to form at least one storage capacitor structure composed of first metal layer, second metal layer and a dielectric layer in middle at the down base; then to form an isolation layer on the inner surface of the upper base and stretch it into the LCD layer to keep the thickness of the LCD layer; then to form a common electrode between the down base and the isolation layer, which are connected with the first metal layer though separately transparent conducting layer.

Description

technical field [0001] The present invention relates to a liquid crystal display device and a manufacturing method thereof, in particular to a liquid crystal display device without linear storage capacitor electrode lines (storage capacitance electrode lines, Cs-lines) and a manufacturing method thereof. Background technique [0002] A liquid crystal display device (LCD) includes an upper substrate and a lower substrate, and a liquid crystal layer sandwiched between the upper and lower substrates. Generally, the upper substrate has a color filter and a common electrode. The lower substrate has gate lines extending laterally, source lines (or data lines) extending vertically, thin film transistors (TFTs) serving as switching elements located near intersections of the gate lines and source lines, and A pixel electrode in an area defined by a gate line and a source line. Each thin film transistor has a gate, a source and a drain. The gate is extended from the gate line, and ...
