Problems solved by technology

[0049] However, the use of acrylic material results in increased cost
Also, although the light transmittance of the acrylic is temporarily increased by the post exposure process, the light transmittance of the acrylic remains reduced during the subsequent process, thereby reducing the light transmittance of the panel

Embodiment Construction

[0063] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0064] 5A to 5D are diagrams sequentially showing the layout of a liquid crystal display having a COT structure according to the present invention.

[0065] Referring to FIG. 5A , in the LCD device having a COT structure according to the present invention, gate lines 202 are horizontally arranged on the array substrate, and common electrode lines 206 are horizontally arranged at certain intervals from the gate lines 202 . Here, the common electrode line 206 includes a data line shielding common electrode 206a vertically arranged to minimize a crosstalk level and a storage capacitor portion 206b horizontally arranged to constitute a storage capacitor. Here, at least two data line shielding common electrodes 206a are arranged to face each other with a certain interval therebetween. Furthermore, in the gate patterning, the g...

Abstract

An array substrate of a liquid crystal display device and a method for fabricating the array substrate are provided. The array substrate includes: a gating line and a data line crossing each other to define a pixel region on the substrate; data line shielding common electrodes arranged at both sides of the data line; a thin film transistor formed at a crossing of the gating line and the data line; a black matrix arranged on a region including the data line and a part of data line shielding common electrodes; a color filter arranged at the pixel region defined by the gating line and the data line crossing each other; and a common electrode and a pixel electrode arranged at the pixel region defined by the gating line and the data line crossing each other.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device capable of preventing light leakage from a COT (color filter on TFT) structure and a manufacturing method thereof. Background technique [0002] Generally, a liquid crystal display device (LCD) displays images using optical anisotropy and birefringence of liquid crystal molecules. When an electric field is applied to the liquid crystal molecules, the alignment of the liquid crystal molecules changes, and the light transmittance also changes as the alignment direction of the liquid crystal molecules changes. [0003] Furthermore, in the LCD device, two substrates respectively having electric field forming electrodes are arranged such that their surfaces having the electrodes face each other, a liquid crystal material is injected between the two substrates, and liquid crystal molecules are charged against the two electrodes. The el...
