PURPOSE:To enable to control the gradations of a liquid crystal when a nonlinear element and the liquid crystal are combined into one, by a method wherein the nonlinear element is constituted of the laminated material, which consists of three layers of the one conductive type non-single crystal semiconductor layer, which is provided on the light-transmitting insulat ing substrate, the intrinsic semiconductor layer, which contains carbon of 1/10 or below and is provided on the one conductive type non-single crystal semiconductor layer, and the non-single crystal semiconductor layer, which has the same conductive type as that of the one conductive type non-single crystal semiconductor layer and is provided on the intrinsic semiconductor layer, and has the characteristics of reversely faced rectification. CONSTITUTION:A first electrode 21 constituted of a light-transmitting conductive film 17 of ITO or SnO2 and a light-shielding Cr electrode 11 is provided on a light-transmitting insulating substrate 20 consisting of non-alkali glass and a composite diode 2 constituted of an N type layer 12 consisting of a non-single crystal semiconductor layer, an I-type layer 13 containing carbon of 1/10 or less and an N type layer 14 is provided on the first electrode 21. Then, a second electrode 22 consisting of an SnO2 or ITO layer 15 and an Al layer 16 is coated on the composite diode 2 and the laminated material is constituted as the NIN type non-linear element. Carbon is made to contain in the I-type layer 13 in such a way and the nonlinear element is made to have the symmetrical V-I characteristics. When this nonlinear element is combined with a liquid crystal provided with the split electrodes, the R, G and B gradations of the liquid crystal can be controlled. |
