Chip on Glass Type Driver Chip and Display Apparatus Including the Same

Abstract

A chip on glass (COG) type driver chip includes a base substrate, at least one insulation layer and at least one line layer alternately stacked on the base substrate, and a bump array disposed on an uppermost layer of the base substrate, wherein the bump array includes a plurality of input bumps passing through the at least one insulation layer and connected to metal lines of the at least one line layer, a plurality of output bumps passing through the at least one insulation layer and connected to the metal lines of the at least one line layer, and a plurality of dummy bumps electrically disconnected from the at least one line layer with the at least one insulation layer therebetween.
