PROBLEM TO BE SOLVED: To provide an active matrix-type in-plane switching mode color liquid crystal display apparatus which has excellent viewing angle characteristics, the manufacturing cost of which is made inexpensive and in which a high-quality big-screen image having hardly display irregularity can be realized. SOLUTION: The in-plane switching mode color liquid crystal display apparatus is provided with: a pair of substrates at least one of which is transparent; a liquid crystal composition layer held between the substrates; a plurality of scanning lines, video signal wires and pixel electrodes, which are paired with common electrodes, all of which are arranged in a matrix mode on the opposed surface of one of the substrates to each other; and a thin-film transistor element connected to the pixel electrodes, the scanning lines and the video signal wires. A connection portion of a protective transistor element, which is connected to both of the common electrodes and the scanning lines and copes with static electricity, and a connection portion of another protective transistor element, which is connected to both of the common electrodes and the video signal wires and copes with static electricity, are formed simultaneously when an element of a thin-film semiconductor layer of the thin-film transistor element is separated by using a halftone exposure technique.
