PURPOSE:To make cell thickness and response speed uniform, to suppress generation of Newton's rings and to make the range of a visual angle wider and the thickness smaller by constituting a liquid display body of the substrates formed with members having different coeffts. of expansion into one body. CONSTITUTION:The upper plastic film 12 of the 1st electrode substrate 1 sandwiching a polarizing film 11 has the coefft. of expansion larger than the coefft. of expansion of a lower film 13 and therefore when said substrate is adhered by an adhesive layer to the 2nd electrode substrate 7 at a high temp. and is allowed to cool to a room temp., the outside thereof is going to curve on the side opposite form a liquid crystal layer 6 but since the substrate 7 is a glass plate and is hardly curved by an environmental change, the substrate 1 is held by spacers 5 and is thus prevented from deforming. The 3rd electrode substrate 2 formed into one body at a high temp. is going to curve into a recessed shape on the side opposite from the layer 6, in the same way as with the substrate 1 because the coefft. of expansion of a plastic film 23 laminated on the liquid 6 side of said substrate is smaller than the coefft. of expansion of a reflecting body 25, but the substrate 2 is held by the spacers 5 and is prevented from deforming. The laminated two layers 6 are thus made respectively uniform. |
