Abstract:
1. A display device comprising: a pair of substrates; a plurality of drive circuit chips arranged on a peripheral portion of one of the substrates, the drive circuit chip having a rectangular shape including a pair of short length sides and a pair of long length sides; a plurality of terminal portions formed on the peripheral portion of the one of the substrates; and a plurality of wiring lines formed on the one of the substrates and connected to the plurality of terminal portions; wherein the drive circuit chip includes a plurality of first bumps and a plurality of second bumps disposed on the drive circuit chip so that both of the plurality of first and second bumps of the drive circuit chip are adjacent at least one of the short length sides of the drive circuit chip, the plurality of second bumps of the drive circuit chip being separated from the plurality of first bumps of the drive circuit chip; wherein one of the plurality of first bumps and one of the plurality of second bumps of the drive circuit chip adjacent the at least one of the short length sides of the drive circuit chip are both connected to one of the plurality of terminal portions on the one of the substrates; and wherein a width of the plurality of first bumps is narrower than a width of the plurality of wiring lines, and a width of the plurality of second bumps is wider than the width of the plurality of wiring lines.
