Abstract
In the art of liquid crystal displays, there is the problem of differential expansion or contraction of components of the display upon changes in temperature. This leads to degradation of the display upon changes in temperature. The liquid crystal display of the invention includes at least a liquid crystal cell and a polarizing sheet. The liquid crystal display of the invention optionally further includes a phase retarder. The components of each of these elements are made of materials such that differences in the linear expansion coefficients among the materials is less than 0.5.times.10.sup.-5 /.degree.C.
