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.
