Abstract:
A method of manufacturing an in-plane switching liquid crystal display apparatus, comprising: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 connected to the thin film transistors, common electrodes opposing the liquid crystal driving electrodes, and common signal lines connected to the common electrodes; 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; 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; providing a liquid crystal layer pinched and held between the array substrate and the counter substrate and which presents birefringence effects; and rejecting the manufactured in-plane switching liquid crystal display apparatus if a difference in transmittance of more than 5% for green light of approximately 544 nm wavelength in a displaying area of the in-plane switching liquid crystal display apparatus occurs, wherein an in-plane retardation of the display apparatus (&Dgr;n)Â·(dmaxâˆ’dmin) is not less than 0 nm and not more than 20 nm in a case a largest gap of gaps between the liquid crystal driving electrodes and opposing substrates within the display surface of the liquid crystal display is denoted dmax, and a smallest gap within the display surface of the liquid crystal display is denoted dmin.
