IPC: G02F1/13
Filed: 1993-01-25
Abstract: PURPOSE:To stabilize gap control and to improve a display contrast by fixing and arranging the spacers of the liquid crystal panel along the spacing between transparent electrodes. CONSTITUTION:This process for production of the liquid crystal panel consists of a patterning stage, baking stage, film forming stage, photolithography stage, peeling stage, assembling stage, etc. The patterns of the transparent electrodes are formed on the substrate surface by using a photoresist in the patterning stage. The photoresist made to remain on the patterns is converted to a lift mask by baking in the baking stage. A photosensitive film is applied at a prescribed thickness on the substrate surface and is prebaked to form the film in the film forming stage. The photosensitive film is exposed from the rear surface of the substrate via the lift off mask (and an additional intersected pattern mask) and is developed to form the spacers matched with the patterned spacings between the transparent electrodes in the photolithography stage. The used lift off mask is peeled in the peeling stage. Finally, a counter substrate is adhered to the substrate via the spacers and a liquid crystal is sealed between both substrates in the assemblingstage.
