Abstract
The present invention has an object to provide a liquid crystal display device which, when a liquid crystal injection portion is sealed and stopped up with a resin, makes it possible to precisely and easily perform the operation and makes it possible to detect defective liquid crystal injection. The liquid crystal display device comprises one substrate on which a metal reflective film is formed, the other substrate arranged opposite to the substrate, a sealing material, interposed between the pair of substrates, for surrounding, together with the substrates, a liquid crystal injection space formed between the substrates, and a liquid crystal sealed into the liquid crystal injection space, and is characterized in that a liquid crystal injection portion is formed on the sealing material, a plurality of display electrodes are formed on a substrate surface in a region in which the liquid crystal is sealed, and, on one of the substrates, outside the display electrode forming region, an unformed portion of the metal reflective film is formed on a portion including the injection portion of the injection material.
