ABSTRACT:
A color optical printer head which can prevent leakage of white light from the interstices between transparent electrodes arranged inside liquid crystal arrays and prevent color mixture, thereby improving color reproducibility. A light blocking layer is formed between transparent electrodes which are adjacently arranged and covered with color filters of different colors and the whole surface which is covered either with the color filter layer or the light blocking layer is further covered with a protecting layer of photo-hardening resin.
