ABSTRACT:
A transmission type or projection type liquid crystal display device includes a light source and an active matrix type liquid crystal display panel provided with a thin film transistor arrangement. A shielding film is included for cutting off light incident upon the thin film transistor arrangement from the light source. Electrode terminals of the liquid crystal display panel and outputs of driving LSI circuits are connected to each other by flexible substrates with the connected portions between the electrode terminals of the liquid crystal display panel and the flexible substrates protected by a connected portion protecting resin. The liquid crystal display device is further provided with a light shielding device for covering at least the protecting resin portion of the liquid crystal display panel, so as to prevent light of the light source from entering the region of the connecting portion protecting resin.
