  • Patent number: 11480839
    Abstract: In a substrate body of an electro-optical device, a first groove, and a second groove extending in a direction intersecting the first groove are formed. A capacitance element is constituted by a layered film that includes a first conductive film, a dielectric film, and a second conductive film sequentially layered in a region including the first groove and the second groove. When the first groove and the second groove intersect, the intersection becomes wide during etching. However, when the first groove and the second groove do not intersect, such as when the first groove and the second groove are spaced apart, a wide portion is less likely to be generated. Accordingly, the first insulating film easily fills the grooves.
