    摘要： A substrate on which spacers are disposed in a certain arrangement state and an optical device using such a substrate are provided. A plurality of spacers are irregularly disposed on a substrate depending on a predetermined rule, so that overall uniform optical characteristics can be ensured without causing a so-called moire phenomenon or the like, while the spacers maintain the uniform cell gap in the construction of the optical device.
