Abstract
A color image recording apparatus employing a liquid crystal shutter array in which a color picture can be recorded with high quality using a small-sized apparatus and without requiring complex operations. A liquid crystal shutter array of the apparatus includes pixel electrodes and a shutter common electrode disposed in opposition to the pixel electrodes with a gap therebetween filled with a liquid crystal, a pair of transparent substrates supporting the pixel electrodes and the shutter common electrode by sandwiching the pixel electrodes and the shutter common electrode therebetween, and polarization plates stacked on the respective outsides of the transparent plates. A color liquid crystal layer is stacked on the liquid crystal shutter array constituted by first and second common electrodes disposed in opposition to each other with the gap therebetween filled with an ECB mode liquid crystal, and a pair of transparent substrates supporting the common electrodes.
