  • Patent number: 11624955
    Abstract: In a liquid crystal device, an intermediate refractive index film including a silicon nitride film, a silicon oxynitride film, or an aluminum oxide film is provided between an oriented film formed of a diagonally vapor-deposited film of silicon oxide and an electrode containing ITO. Thus, because there are no interfaces having a large refractive index difference between the oriented film and the electrode, reflection between the oriented film and the electrode can be suppressed. A high density silicon oxide film is formed between the intermediate refractive index film and the oriented film. The high density silicon oxide film is formed by an atomic deposition method, thus is appropriately formed inside a contact hole.
