ABSTRACT:
A principal object of the present invention is to provide a substrate for a liquid crystal display not undergoing mura called gravity defect because the amount of deformation in a small load region is large and having a uniformity of the panel and an adequate recovery factor against a local load. In order to achieve the aforementioned object, the present invention provides the substrate for a liquid crystal display comprises at least a transparent substrate and a columnar spacer formed on the transparent substrate. The substrate is characterized in that the amount of initial deformation A of the spacer measured by a predetermined measurement method is 0.04 μm or more and the amount of plastic deformation B is 0.7 μm or less.
