Abstract

A method and apparatus for suppressing errors in a disconnecting inspection of wiring lines formed over a TFT substrate utilized for a liquid crystal display panel due to a defective contact between an inspection probe and an inspection terminal. A liquid crystal display has a liquid crystal display panel including a pair of substrates and a liquid crystal layer with a plurality of gate lines and a plurality of data lines formed on a main surface of one of the substrates adjacent to the liquid crystal layer. The plurality of gate lines extend in one direction, and the plurality of data lines extend in another direction transverse to the one direction and are spaced from the plurality of gate lines by a first insulating film. Switching elements and pixel electrodes are formed on the main surface. At least one of at least one of the plurality of data lines and at least one of the plurality of gate lines is electrically connected with an inspection terminal, and the inspection terminal extends at least partially over a second insulating film covering at least two other data lines disposed at one side of the at least one data line or at least two other gate lines disposed at one side o…
