Abstract
An object of the invention is to reduce the size of a liquid crystal display device and to enhance the reliability of a connection portion with a flexible wiring substrate. According to the invention, liquid crystal is sandwiched between a TFT substrate and a color filter substrate. The TFT substrate is formed in a larger size than that of the color filter substrate. A connection portion with a flexible wiring substrate is formed on the TFT substrate. The TFT substrate is formed with a notch at its portion connected with the flexible wiring substrate. The flexible wiring substrate is bent over the notch toward a rear side of the liquid crystal display device as accommodated in a mold. This allows for the size reduction of the overall display device and ensures the enhanced reliability of the connection portion.
