Abstract:
1. A liquid crystal display device with data switching thin film transistors for inspection, comprising: a pixel matrix where a plurality of gate lines and a plurality of data lines cross each other and a plurality of liquid crystal cells are arranged; first data switching thin film transistors respectively and directly connected to data lines of a first data line group of the data lines and directly connected to a first external wire connected to a first external pad; and second data switching thin film transistors respectively and directly connected to data lines of a second data line group of the data lines and directly connected to a second external wire connected to a second external pad; wherein the first group of data lines are a bunch of adjacent data lines in the middle of the pixel matrix and the second group of data lines are two bunches of adjacent data lines on either sides of the first group of data lines, and wherein a first data is supplied to liquid crystal cells of the middle of the pixel matrix by the first data switching thin film transistors and a second data is supplied to liquid crystal cells of the sides of the pixel matrix by the first and second data switching thin film transistors when inspecting cross-talk.
