Abstract
A display apparatus for underwater use comprises a hermetically sealed enclosed including a liquid crystal display device. The device comprises a liquid crystal cell disposed between layers of light polarizers and a light reflector. The combination of cell, polarizers and reflector displays either bright images on a dark background or the reverse. To make the edges of the cell substantially invisible, for improving readability of the display, the liquid crystal cell is surround by a matting comprising the identical layers of light polarizers and reflector used in combination with the liquid crystal cell. A common matting can be used with a mosaic of cells to create the appearance of a single, large area cell, or with several cells to display independent images.
