PURPOSE:To curtail a panel manufacturing material by constituting the title device of a liquid crystal panel, a phase plate consisting of a birefringent film which has brought a high polymer film to multidirection drawing, a polarizing plate and a means for applying a voltage to the liquid crystal panel. CONSTITUTION:As for this X-Y matrix panel, an LV 11 is constituted by placing a liquid crystal 4 between a transparent line electrode (ITO) 3 and a transparent row electrode 5 consisting of indium oxide, etc. provided on a pair of glass substrates 2, 6, respectively. Also, said pair of ITOs are placed so as to be orthogonal to each other, and an intersection part of both the electrodes constitutes one picture element. TN and STN cells are driven successively by a regular voltage averaging method so as to apply the maximum effective voltage ratio to an ON cell and an OFF cell. In such a case, a high polymer film phase plate 12 to which a prescribed birefringent property are provided by drawing, etc. such as cellulose, polyester, cellulose acetate, etc. is used by laminating it on the matrix panel. According to such a phase plate, the characteristic of the panel is equalized synthetically and the manufacturing yield can be improved. |
