Abstract

PURPOSE:To lower a dark level by providing >=2 display patterns to an upper and a lower substrates in the same plane, and making the directions of light- distribution treatments of display patterns of one substrates different according to the wavelength of incident light. CONSTITUTION:Respective display patterns which consist of display patterns of a red part 1a, green part 1b, and blue part 1c and provided on two upper and lower substrates 2 and 3 are treated by liquid crystal treatments in different directions as shown by arrows A and B, C and D, and E and F. For the anisotropic light-distribution, a mask having windows corresponding to only the areas of display patterns of 1a-1c is arranged and oriented films are rubbed in a direction ANF. The obtained substrates 2 and 3 are stuck together with seal resin and cured thermally and then twist nematic type liquid crystal is charged to manufacture a panel 1. Then, a filter plate 4 having color filters of red, green, and blue corresponding to the respective display patterns is stacked on the panel 1. Thus, the device with a low dark level is manufactured at low cost.
