IC chip mounting structure and display device
First Claim
1. An IC chip mounting structure comprising:
- at least one IC chip having a first surface having electrodes formed thereon and a second surface opposite to said first surface;
a wiring board having said IC chip mounted thereon and conductors connected to the electrodes of said IC chip;
a protective member attached to said wiring board and having an opening comprising a peripheral wall surrounding said IC chip; and
a heat conductive first member arranged in said opening of said protective member in contact with said second surface of said IC chip.

Abstract
IC CHIP MOUNTING STRUCTURE has IC chips having protruding electrodes, a flexible printed circuit board having conductors connected to the protruding electrodes of the IC chips, and a protective plate attached to the flexible printed circuit board. The protective plate has openings to accommodate the driver IC chips. A resin member having a high heat conductivity is arranged in the opening in contact with the surface of the IC chip. The IC chip mounting structure can be attached to a chassis of a plasma display device so that heat generated by the driver IC chip is transferred to the chassis via the heat conductive resin member.
