发明名称 Liquid crystal device and electronic apparatus
摘要 A first peripheral electrode and a second peripheral electrode are provided at a peripheral region sandwiched between a pixel region and a seal material in a first substrate of a liquid crystal device, and strength of electric potentials which are applied to the first peripheral electrode, the second peripheral electrode, and a common electrode of an opposite substrate satisfies the condition of the second peripheral electrode<the common electrode<the first peripheral electrode. Therefore, electric fields are formed between the first peripheral electrode and the common electrode, between the second peripheral electrode and the common electrode, and between the first peripheral electrode and the second peripheral electrode.
