  • Patent number: 8964147
    Abstract: An electro-optic device is provided. In the electro-optic device, when a groove is sealed to be hollow, a sacrificial film is formed in the groove before forming a first sealing film, the first sealing film is formed, and then the sacrificial film is removed through a penetration portion of the first sealing film. A second sealing film is formed on the first sealing film, and the penetration portion of the first sealing film is blocked by the second sealing film. For this reason, it is possible to form the first sealing film to block an opening portion of the groove, and it is possible to prevent the first sealing film from being formed up to the inside of the groove.

  • Publication number: 20150013799
    Abstract: A component attaching structure for attaching a first component and a second component to each other. The first component has an attachment hole and an internal thread formed therein. The second component has an external thread formed thereon. The second component supports a sealing member, which seals an interface between an outer circumferential surface of the second component and an inner circumferential surface of the attaching hole at a position closer to a tip end of the second component than the external thread. If the direction in which the second component moves relative to the first component when the second component is attached to the first component is defined as an attaching direction, a distance between the external thread and the sealing member in the attaching direction is greater than the length of the internal thread in the attaching direction.
