Dichroic dyes and application in liquid crystal display was studied.The blue dyes absorb leaked red and yellow background-light especially in oblique direction at dark state
and the dyes dont absorb light when turning following LC molecules at white state
so the contrast of TN-LCD is improved because red and yellow light are main part in back-light
and humans eyes is more sensitive to them. As results
the contrasts of three samples are improved to 54.92
67.77 and 50.30 from 47.87
60.32 and 42.04;the steepnesses are leaned over 1.56
1.55
1.58 from 1.41
1.39
1.40 for increasing grey scale;the viewing angle is improved as the curve of contrast with 10 and 20 by 5 on the left and right.
