Patent ID: 7852423

Claim:
A liquid crystal display (LCD) device, comprising: a liquid crystal panel; a backlight unit; a main support supporting the liquid crystal panel and the back light unit; a data printed circuit board attached to the liquid crystal panel to provide driving signals to the liquid crystal panel using power received by a connector formed on the edge of the printed circuit board, wherein the connector is connected to a external power source; a gate printed circuit board for driving gate lines in the liquid crystal panel; a separation part arranged between the data printed circuit board and a main support and creating a space therebetween to dissipate heat from the data printed circuit board, wherein the one part of the separation part is in direct contact with the main support and the other part of the separation part is in direct contact with the data printed circuit board, and wherein the contact surface between the main support and the one part of the separation part faces the contact surface between the data printed circuit board and the other part of the separation part, and wherein the separation part is formed as a single unit on an entire edge of the data printed circuit board; and at least a tape carrier package to electrically connect the liquid crystal panel to the data printed circuit board, wherein an edge of the separation part protrudes toward the tape carrier package further than the edge of the data printed circuit board, and wherein the edge of the separation part is not in contact with the space.
