1. A substrate for a liquid crystal panel comprising:
- a substrate;
a first shading region arranged on said substrate and defining an outer edge of a display region;
a cell thickness adjustment layer arranged on said substrate inside said display region; and
a second shading region arranged on said cell thickness adjustment layer and defining boundaries of a plurality of pixel regions inside said display region;
wherein a thickness of said cell thickness adjustment layer is selected so that a height of said second shading region as a whole is not less than a height of said first shading layer as a whole;
wherein said first shading region includes a superposition of coloring layers of a plurality of colors and an overcoat layer; and
wherein said second shading region includes a superposition of coloring layers of a plurality of colors and an overcoat layer.

Abstract
A first shading region for defining a display region is arranged on a light-transmitting substrate. A cell thickness adjustment layer is arranged on the substrate inside the display region and a second shading region for defining a boundary of a plurality of pixel regions is arranged on the cell thickness adjustment layer. The cell thickness adjustment layer is selected so that the total thickness of the second shading region is not smaller than the total thickness of the first shading region. The cell gap can thus be made uniform throughout the whole display region and non-uniformity of display can be prevented.

9. A method of producing a substrate for a liquid crystal panel comprising:
-
a first step of forming a first shading region defining an outer edge of a display region on a substrate;
a second step of forming a cell thickness adjustment layer on said substrate inside said display region; and
a third step of forming a second shading region on said cell thickness adjustment layer and defining boundaries of a plurality of pixel regions inside said display region;
wherein a thickness of said cell thickness adjustment layer is selected so that a height of said second shading region as a whole is not less than a height of said first shading region as a whole;
wherein said first step forms said first shading region by serially laminating coloring layers of a plurality of colors and an overcoat layer; and
wherein said third step forms said second shading region by serially laminating coloring layers of a plurality of colors and an overcoat layer. - View Dependent Claims (10, 11, 12, 13, 14)
