The present invention relates to a liquid crystal light valve used especially in projection type liquid crystal units. It is an object of the present invention to provide a projection type liquid crystal display unit with improved display qualities by enhancing display brightness and preventing nonuniform and poor orientation of liquid crystal molecules. A pixel array region 4, on which display electrodes consisting of thin aluminum (Al) films as light reflecting films are formed for each pixel, is formed on a silicon substrate 2, and a counter electrode 16 is provided on a glass substrate 14 which is the counter substrate. The silicon substrate 2 and the glass substrate 14 face to each other, and bonded by narrow wall of spacers 6, 8, 10 and 12 consisting of an adhesive and photosensitive resin. Liquid crystals 18 are enclosed in the region between the pixel array region 4 and the counter electrode 16. No spacers are formed on the pixel array region 4. The spacers 6-12 bond upper and lower substrates outside immediate to the pixel array region 4, in order to make the thickness between the pixel array region 4 and the counter electrode 16 (cell gap) of high precision. <IMAGE> |
