Abstract
A display device includes a TFT substrate with gate signal lines, drain signal lines, thin-film transistors connected thereto, a gate driver connected to the gate signal lines, a drain driver having output terminals connected to drain signal lines, and a film substrate having first wirings. The first wirings are disposed between the drain driver and the film substrate. The drain driver is mounted on the film substrate, and the output terminals are connected to the first wirings between the film substrate and the drain driver. The output terminal includes first group terminals formed in parallel with a longer edge of the drain driver, and second group terminals formed in parallel with the longer edge and disposed between the loner edge and the first group terminals.
