PROBLEM TO BE SOLVED: To make a reflection layer possible to adjacent to a liquid crystal layer, to eliminate a doubly seen display and to enable bright color display, by irradiating a light molecule- dispersed liquid crystal layer with UV rays from the front surface substrate side, then arranging a transparent sustrate opposite to the front surface substrate via an air layer. SOLUTION: Transparent electrodes 4 for display are formed on the front surface of the front surface substrate 1 and pixel electrodes 5 for display in common use as the reflection layer are formed on the surface of the rear surface substrate 2. The high molecular material dispersed liquid crystal layer 3 held between the substrates is formed by irradiating a soln. mixture composed of liquid crystals and a high molecule precursor, such as acryl monomer, with UV rays to cause a phase sepn., and to fill the liquid crystals in the network spacings of the high-polymer resin. The front surface of the transparent substrate 6 is provided with the red, green and blue color filters 7r, 7g, 7b as the color filters according to the positions of the transparent electrodes 4 for display and the pixel electrodes 5 for display. The color filter forming surface and the front surface substrate 1 face each other via the air layer 8. The pixel electrodes 5 for display in common use as the light reflection layer are disposed adjacently behind the high molecular material-dispersed liquid crystal layer 3 so that the display is not visible in double and the bright display is obtd. even when the display is viewed from a diagonal direction.
