Abstract: A method of manufacturing an in-plane switching liquid crystal display apparatus which includes forming on a TFT array substrate, a plurality of scanning signal lines, a plurality of image signal lines each crossing the scanning signal lines, thin film transistors at each intersection of the scanning signal lines and image signal lines, liquid crystal driving electrodes opposing the liquid crystal driving electrodes, and common signal lines connected to the common electrodes. Further, the method includes opposing a counter substrate to the TFT array substrate, interposing a plurality of spacers in a gap between the TFT array substrate and the counter substrate, and interposing a sealing agent in the gap between the TFT array substrate and the counter substrate so as to adhere the TFT array substrate and the counter substrate at peripheral portions thereof.
