Abstract
Disclosed is an IC chip using a glass substrate capable of being manufactured at a lower cost than the IC chip using from a semiconductor wafer. Further, where the body substrate of a display device is made of glass, the IC chip and the body substrate can have equal coefficients of thermal expansion, thus preventing the IC chips from peeling off and reducing the failure rate. Furthermore, the gate line driving IC applied to a display device can be arranged as an IC chip having a length approximately equal to the display area, therefore, mounting a plurality of IC chips as the gate driving IC is not required, thereby reducing the production cost. Still further, all gate lines can be extended in parallel from the IC chip so that no difference in the delay occurs among the gate lines and the size of frame of display device can reduced.
