Abstract
A liquid crystal device is provided that comprises a plurality of R colored layers, a plurality of G colored layers, and a plurality of B colored layers that are formed on either one of a pair of substrates and are aligned in a predetermined arrangement in plan view, a light-shielding layer formed between the colored layers, and a plurality of spacers formed on either one of the pair of substrates and protruding toward the other substrate. The plurality of spacers is formed around the B colored layers and/or the R colored layers, but is not formed around the G colored layers. Thus, even if a positional deviation occurs between the substrates, the spacers do not get into the G colored layers.
