Abstract

A plurality of gate lines and a plurality of data lines intersecting the gate lines to define a display area are formed on an insulating substrate including a display area and a surrounding area. On the surrounding area, a gate driving circuit connected to the gate lines and a logic circuit for VI interposed between the gate driving circuit and the gate line and having several first to third NOR gates are formed. A first input terminal of the first NOR gate of the logic circuit for VI is connected to an output terminal of the gate driving circuit, and a second input terminal thereof is connected to a CON1 terminal, and an output terminal thereof is connected to a first input terminal of the second or the third NOR gate. A second input terminal of the second NOR gate is connected to a CON2 terminal and an output terminal thereof is connected to the gate lines in odd number. A second input terminal of the NOR gate is connected to a CON3 terminal and an output terminal thereof is connected to the gate lines in even number.

Description

technical field

[0001] The present invention relates to a thin film transistor array panel, in particular to a visual inspection (visual inspection) device and a method for performing visual inspection in a thin film transistor array panel in which a gate driving circuit is integrated. Background technique

[0002] The thin film transistor array panel is used as a circuit board for independently driving each pixel in a liquid crystal display (LCD) or an organic electroluminescence (EL) display, etc. In the thin film transistor panel, scanning signal lines or gate lines, and image signal lines or data lines for transmitting image signals. Also formed are thin film transistors connected to gate lines and data lines, pixel electrodes connected to the thin film transistors, a gate insulating layer for covering and insulating the gate lines, and a gate insulating layer for covering and insulating the thin film transistors and data lines. passivation layer. ...
