<p>PURPOSE:To realize thin cell thicknesser with good accuracy and to increase operating speeds, by providing plural pieces of projecting parts on the lower part of an upper plate facing a lower plate disposed with driving elements like a matrix, and controlling the thicknesses of liquid crystal layers. CONSTITUTION:Projecting parts 11 and a transparent conductive film 12 are formed on the lower part of an upper plate 10 consisting of a transparent material to determine the space from a lower plate 1. The parts 11 are so disposed as to contact with the insulating film 13 of the plate 1. The height of the parts 11 can be made to 1mu if chemical etching or ion etching is used. An insulating film 24 is provided in the case of AC driving, and serves as a protecting film for aluminum electrodes 23. Provision of said film is desirable because said film permits satisfactory matching with liquid crystals 25. Projecting parts 27 of an upper plate 26 may be disposed so as to contact with the surface of the film 24 on the aluminum electrodes of a lower plate 15. Since the packaging under exertion of pressure from above is possible, the packaging is easy despite the presence of strains in the lower plate.</p> |
