Abstract
A display device made of a TFT substrate and a driver IC is configured to eliminate bad connection between them. On the driver IC connected to the TFT substrate, a first principal surface has first bumps formed along a first side having a first edge and second bumps formed along a second side opposite to the first side and having a second edge. The TFT substrate has first terminals and second terminals connected to the first and the second bumps, respectively. On a cross section taken perpendicularly to the first and the second sides, the first principal surface has a first area between the first and the second bumps and a second area between the second bumps and the second edge. The first and the second areas are bent toward the TFT substrate.
