Abstract
A liquid crystal display is constructed by arranging two transparent substrates (1,1') in parallel fashion, using only one polarizer. The display has an active display area for displaying characters that have an embossed appearance. A single polarizer (8) is on the back side of one substrate (1), and a birefringent film (5) is on the front side of the other substrate (1'). The background (15) and the embossed appearing characters (10) have substantially the same appearance, but are differentiated from each other by a dark border (12), thus rendering the characters with an embossed appearance. The border has a substantially different appearance from the embossed appearing characters and the background, the border being preferably darker than the background. The transparency of the embossed appearing characters and the background are within about .+-.10% of the other.
