摘要:
The liquid crystal display apparatus of present invention includes a TFT array substrate on which there are formed scanning signal lines, image signal lines, thin film transistors, liquid crystal driving electrodes, common electrodes and common signal lines, a counter substrate which opposes the TFT array substrate, primary spacers for maintaining a gap between both substrates constant, secondary spacers for maintaining a gap in peripheral portions of both substrates constant, a seal member which is interposed in the gap between both substrates together with the secondary spacers and which adhere peripheral portions of both substrates, and a liquid crystal layer, wherein the in-plane retardation of the display apparatus (.DELTA.n).multidot.(d.sub.max -d.sub.min) is not less than 0 nm and not more than 20 nm, whereby variations in colors occurring in liquid crystal display apparatuses of IPS type which are due to unevenness of liquid crystal layers can be eliminated.
