PURPOSE: To make cell thickness constant and response speed uniform and to prevent generation of Newton's rings by using plastic substrates formed integrally with polarizing films in constituting a liquid crystal display body of a reflection type.
CONSTITUTION: Spacers 5 such as glass fibers are disposed in a liquid crystal layer 6, and upper and lower electrode substrates 1, 2 sandwich polarizing plates 11, 21 therebetween. Plastic films 12, 22, 13, 23 are formed into one body with the films 11, 21. The film 13 (on the layer 6 side) of the substrae 1 sandwiching the film 11 has the coefft. of expansion smaller than the coefft. of expansion of the film 12 on the other side and therefore the substrate 1 subjected to straining at a high temp. is going to curve into a recessed shape toward the outside at an ordinary temp. or in the service temp. range. The film 23 of the substrate 2 on the layer 6 side has the coefft. of expansion smaller than that of the body 25 and therefore the substrate is going to curve into a recessed shape toward the outside opposite from the substrate 1. There are, however, the spacers 5 in the layer 6 and since the spacers 5 are hard, the substrates 1, 2 are not compressed to the thickness of the spacers 5 or below and the uniform thickness of the cell is maintained over the entire part.
