Problems solved by technology

[0042] However, the configuration of the gate drive circuit 60 described in Patent Document 1 has a problem in that the gate drive circuit wiring 46 that supplies signals to each segment ST is arranged between the gate drive circuit 60 and the substrate edge 26 . That is, the branch line 78 arranged outside the gate drive circuit 60 and connecting the gate drive circuit wiring 46 and each TFT element in the gate drive circuit 60 becomes long, and a disconnection defect or the like is likely to occur.

Abstract

A gate drive circuit (60) divided into a plurality of stages (ST) is provided. In each of the stages (ST), TFT elements (T1-T4) are provided, and branch lines (78) which connect clock lines (72, 74) and the TFT elements are provided. When attention is paid to one branch line (78A), divergent lines (79A, 79B) which electrically connect TFT elements (T2, T4) provided in a stage (ST(j)) different from a stage (ST(j-1)) in which TFT elements (T1, T3) connected to the branch line (78A) are provided and the branch line (78A) are provided to extend from the branch line (78A).

Description

Technical field [0001] The present invention relates to an array substrate provided with TFT elements and the like on an insulating substrate, and a liquid crystal display panel using the array substrate. Background technique [0002] Active matrix display devices that use thin film transistors (hereinafter referred to as “TFTs”) as switching elements of pixels have fast response speeds and are easy to perform multi-gray-scale display. They are used in mobile phones, such as televisions, It is widely used in portable game consoles and car navigation devices. [0003] In an active matrix display device, a TFT array substrate and a counter substrate are generally arranged to face each other, and display elements (liquid crystal, organic EL, etc.) are enclosed between these substrates by a sealing material. [0004] (TFT array substrate) [0005] Below, according to Picture 12 The outline structure of the TFT array substrate will be described. [0006] Picture 12 It is a plan view showin...
