ABSTRACT:
The main object of the present invention is to provide a substrate for a monochrome liquid crystal display apparatus having the excellent evenness of the gap between the substrate for a monochrome liquid crystal display apparatus and the counter substrate, capable of displaying with a preferable image quality without the brightness irregularity.In order to achieve the above-mentioned object, the present invention provides a substrate for a monochrome liquid crystal display apparatus comprising a substrate, a black matrix formed in a pattern on the substrate, a protection layer formed on the substrate so as to cover the black matrix, and a columnar spacer formed in the area with the black matrix formed of the protection layer, for adjusting the gap between the substrate and the counter substrate, wherein the height from the surface of the substrate to the upper surface of the columnar spacer provided in the pixel part of the substrate is higher than the height from the substrate surface to the upper surface of the columnar spacer provided in the outer peripheral part as the pixel part peripheral area of the substrate by in a range of 0 μm to 0.8 μm.
