Photoconductor coupled liquid crystal light valve and method for manufacturing the same.

摘要

A photoconductor coupled liquid crystal light valve is disclosed comprising at least a pair of transparent electrodes (3), a liquid crystal layer (2) and a photoconductive layer (1) showing blocking properties both sandwiched between said transparent electrodes (3), wherein said photoconductive layer (1) includes a light absorbing layer (21) and a blocking layer (31) having a band gap wider than said light absorbing layer (21), both said light absorbing layer (21) and said blocking layer (31) being formed of non-alloy a-Si. The invention also includes a method for manufacturing said photoconductor coupled light valve wherein said photoconductive layer (1) is prepared by an electron cyclotron resonance method. <IMAGE>
