Abstract:
1. A liquid crystal display device including a liquid crystal display panel which sandwiches liquid crystal in the inside thereof sealed by a TFT substrate, a color filter substrate and a sealing portion, and a flexible printed circuit board which is mounted on the TFT substrate, wherein the TFT substrate has an area larger than the color filter substrate, a plurality of scanning lines extend in a lateral direction and are arranged parallel to each other in a longitudinal direction, a plurality of data signal lines extend in the longitudinal direction and are arranged parallel to each other in the lateral direction, and terminal portions corresponding to the scanning lines are formed on the TFT substrate, the terminal portion is arranged at a region that is not covered by the color filter substrate, the terminal portions are formed as a unit for every flexible printed circuit board, and the terminal portions and the scanning lines are connected by auxiliary lines and connection lines in order from the terminal portions, the connection lines are arranged in a region covered with the color filter substrate, a width of the connection line at a peripheral portion of the unit is set larger than the width of the connection line at a center portion of the unit, the auxiliary line between the terminal portion and the connection line is formed of a straight line, and a width of the auxiliary line is 20 μm or more and is set larger than the width of the connection line at the center portion of the unit, and the auxiliary lines extend to both the region that is covered by the color filter substrate and the region that is not covered by the color filter substrate.
