Patent ID: 6930744

Claim:
A liquid crystal display (LCD) device comprising: a LCD panel including first and second glass substrates for defining a plurality of pixels arranged in a matrix, and a LC layer sandwiched between said first glass substrate and said second glass substrate, and a drive semiconductor chip mounted on a mounting area of said first or second glass substrate for driving said LCD panel, said drive semiconductor chip having a plurality of input electrodes and a plurality of output electrodes, said first glass substrate mounting thereon a plurality of internal leads, a plurality of extensions each extending from said internal leads to form a distal end of said each extension, a plurality of contact pads each formed on one of said extensions, a plurality of external leads connected to external terminals of said LCD panel, and a plurality of electrode pads each disposed at an end portion of one of said internal leads, said electrode pads being electrically connected to said input and output electrodes of said semiconductor chip, and said contact pads are arranged at a pitch which is larger than a pitch of said electrode pads for said internal leads, the pitch of said internal leads being larger in the vicinity of the distal end of the extension than in the vicinity of said electrode pads, wherein at least one of said contact pads is disposed inside said mounting area.
