发明名称 SEMITRANSMISSIVE LIQUID CRYSTAL DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a semitransmissive liquid crystal display device capable of reducing a light leak and coloration during black display. <P>SOLUTION: The semitransmissive liquid crystal display device 10 has a first &lambda;/2 plate 18 between a first polarizing plate 11 and a counter substrate 12 and a second &lambda;/2 plate 19 between a second polarizing plate 15 and a TFT substrate 14. The angle &theta;1 between the direction of the optical axis of a liquid crystal layer 13 and the polarizing direction of light incident on the liquid crystal layer 13 is so set that 0<&theta;1<45&deg;, desirably, 0&deg;&le;&theta;1&le;22.5&deg;. <P>COPYRIGHT: (C)2007,JPO&INPIT
