LCD and fabrication method thereof having a pedestal and overlying organic film at a periphery of the display
First Claim
1. A liquid crystal displaying apparatus, comprising:
- a first substrate;
a plurality of scanning lines and signal lines on said first substrate in a matrix fashion;
a plurality of switching devices each disposed in the vicinity of an intersection of said scanning lies and said signal lines;
a plurality of pixel electrodes, connected to said switching devices, in a display area;
an organic film formed at a periphery of said display area;
a pedestal on said first substrate and underneath an edge portion of said organic film;
a second substrate opposed to said first substrate; and
a liquid crystal material filled in a space between said first substrate and said second substrate,wherein the thickness of said organic film on said pedestal is thinner than the thickness of said organic film on a non-pedestal area, andwherein the thickness of said pedestal is thinner than the thickness of said organic film on said non-pedestal area.

Abstract
A liquid crystal displaying apparatus is disclosed, that comprises a pair of substrates, a liquid crystal material filled in the space between the pair of substrates, a plurality of lines formed on one of the pair of substrates, an organic film formed on the plurality of lines, a conductive film formed on the organic film, and a pedestal, wherein the plurality of lines extend from a first area to a second area, the organic film being disposed on the plurality of lines in the first area, the second area exceeding an edge portion of the organic film, wherein the pedestal is disposed between the first area and the second area through the edge portion, wherein the organic film is formed between the pedestal to a non-pedestal area, wherein the thickness in the vicinity of at least the edge portion of the organic film formed on the pedestal is smaller than the thickness of the organic film formed in the non-pedestal area, and wherein the thickness of the pedestal is smaller than the thickness of the organic film formed in the non-pedestal area.
