1. A substrate for a LCD device comprising:
a transparent plate;
switching elements for respective pixels, formed on the plate;
protrusions for the respective pixels, formed on the plate in such a way as to protrude to a vicinity of an outermost surface
of the substrate;
each of the protrusions raising an electrode of a corresponding one of the switching elements to the vicinity of the outermost
surface in a corresponding one of the pixels;
a planarization layer formed in such a way as to cover the switching elements, the protrusions, and the electrodes of the
elements in all the pixels, a surface of the planarization layer forming the outermost surface, the planarization layer having
at least one contact hole formed over each corresponding protrusion, partially exposing the electrodes;
pixel electrodes for the respective pixels, formed on the outermost surface; and
each of the pixel electrodes being contacted with a corresponding one of the electrodes of the switching elements in the vicinity
of the outermost surface.
