Claim:
1. A device substrate, comprising: a substrate; a patterned light-shielding layer disposed on the substrate and having a plurality of pixel openings and a plurality of first exposure openings, wherein one of the first exposure openings and one of the pixel openings have different areas and/or shapes; a plurality of first spacers disposed on the substrate, and vertical projections of the first spacers respectively overlap the first exposure openings, wherein a height of each of the first spacers is in a range of 1 micrometer to 6 micrometers; and a plurality of second spacers disposed on the substrate, and vertical projections of the second spacers are located outside the first exposure openings respectively, wherein (a) when a material of the first spacers and the second spacers is a negative photoresist, the height of each of the first spacers is larger than a height of each of the second spacers; and (b) when the material of the first spacers and the second spacers is a positive photoresist, the height of each of the second spacers is larger than the height of each of the first spacers.
