成する印刷法とがある。The black stripe formation method involves applying a photosensitive resin onto the substrate, aligning the substrate and a photomask for forming the black stripe (mask alignment), and then
There is a photolithography method in which black stripes are formed between display electrodes by exposure and development, and a printing method in which black stripes are formed by printing dye or the like between display electrodes using a printing plate.

下を招いている。Problems to be Solved by the Invention In the case of photolithography, it is necessary to align a photomask when exposing a photosensitive resin. As display electrodes become more precise and have a larger capacity, it is necessary to perform mask alignment over a larger area with higher precision than ever before. Therefore, due to poor mask alignment, spacers often cannot be formed at predetermined positions, resulting in a decrease in yield.
