摘要:
A drive element mount display is provided which achieves fine output pad pitches for a display panel driver without reducing the pitches of the connection terminals of display panel wires which connect to the display panel driver. In a liquid crystal driver mount display 1, liquid crystal display means 2 connects to a liquid crystal driver 3 via a driver socket 4a. On the driver socket 4a, the connnection terminals for the liquid crystal display means 2 have larger pitches than the connection terminals for the liquid crystal driver 3. The design eliminates the need to secure a large wiring region on a glass substrate 10, even when the liquid crystal driver 3 is mounted to the glass substrate 10 of the liquid crystal display means 2.
