Abstract

A liquid crystal display (LCD) is provided having transistors disposed within via holes having elongated (e.g., rectangular or oval) contact areas. The use of via holes having elongated contact areas allows an opaque mask defining an aperture for light transmission to be lengthened, thereby increasing the overall area of the aperture. The increase in the area of the aperture may increase the amount of light that can pass through the aperture.
