ABSTRACT:
A liquid crystal display device and a liquid crystal projector using the same are provided for suppressing reduction in liquid crystal properties due to heat and light by precisely shielding light in regions other than a region irradiated with light corresponding to effective pixels. Light-shielding substrates are each brought to absolute contact with a back of a drive substrate and a front of an opposed substrate, respectively. One of the light-shielding substrates is provided with a frame-shaped light-shielding film formed in a region on a surface of a transparent substrate opposed to a non-irradiated region in the drive substrate. Similarly, the other of the light-shielding substrates is provided with a frame-shaped light-shielding film formed in a region on a surface of a transparent substrate opposed to a non-irradiated region in the opposed substrate. The light-shielding films each have an excellent light-shielding property with optical density of 3.0 or above, for example. The light-shielding films are thinly formed in order to suppress stress strain, that is, warpage of glass, due to an adhesive for bonding the light-shielding films to the drive substrate and the opposed substrate, respectively. The light-shielding films are made of a conductive film such as aluminum (Al) and grounded. As a result, the light-shielding films have a function of electrically shielding the liquid crystal display device besides the light-shielding function.
