Embodiment Construction

[0026] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] An LCD device that does not include a connection substrate for connecting a gate driver will be described with reference to the accompanying drawings. As shown in FIG. 13, the LCD device includes an LCD panel 20 configured with driver TAB members 2 and 7 for driving gate and data electrodes, respectively. The LCD panel 20 includes a liquid crystal layer sandwiched between a pair of substrates. The LCD panel 20 includes a pixel array area 8 surrounded by a peripheral area or edge area. In the edge area, the driver TAB members 2 and 7 are connected to the edge area of ​​the LCD panel 20 in order to drive the LCD panel 20 . Each gate driver TAB member 2 includes a gate driver LSI 3 mounted on a TAB tape. A group of wirings 6 for gate drivers is provided on the edge area to serve as interconnection lines such as power supply lines and signa...

Abstract

A liquid crystal display (LCD) panel includes a pixel array region surrounded by a peripheral edge region. Gate driver TAB members are connected to the edge region. A group of lines for gate drivers which connects the gate driver TAB members is formed in the edge region. A shield layer which covers the group of lines for gate drivers is formed in the edge region.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2006-204968 filed on July 27, 2006, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a liquid crystal display (LCD) device, and more particularly, to an LCD device having a structure in which a set of wirings for connecting a gate driver is formed on an LCD panel. Background technique [0003] LCD devices are widely used as display units of audio video (AV) equipment or office automation (OA) equipment because of advantages such as thin profile, light weight, and low power consumption. The LCD device has an LCD panel in which a liquid crystal (LC) material is sandwiched between two substrates. Switching elements such as thin film transistors (TFTs) are arranged in a matrix on one substrate. Hereinafter, a substrate having TFTs is referred to as a TFT substrate. A color filter (CF) layer, a black matrix (BM) layer,...
