Abstract
A liquid crystal display device which can prevent the generation of bubbles on an adhesive surface between a liquid crystal display panel and a face plate which protects the liquid crystal display panel is provided. In mounting the face plate on an upper polarizer of the liquid crystal display panel by way of an adhesive material, a picture frame is formed on a periphery of the face plate for enhancing design property. Although the picture frame is formed by printing black ink, a quantity of Si present in the black ink is set to not more than 0.7% and not less than 0.01% thus preventing the generation of bubbles attributed to defective adhesion between the face plate and the adhesive material.
