Abstract
A liquid crystal display panel having uniform cell thickness is composed of a first substrate and a second opposed substrate where each substrate has cooperating electrodes selectively disposed on the interior surfaces thereof. At least one of the substrates is a laminate of two flexible plastic films and a polarizing film therebetween. The plastic films have different thermal expansion coefficients, with the thermal expansion coefficient of the film on the interior surface being less than the thermal expansion coefficient of the film on the opposed substrate so that the center of the substrate is biased convexly towards the opposed substrate. Substantially rigid spacer members are disposed between the substrates. Adhesive substances are disposed about the periphery of the substrates for coupling the substrates and maintaining the display panel assembled. The at least one substrate is a laminate biased against the spacer members for maintaining uniform thickness across the display panel.
