Patent ID: 7605400

Claim:
A liquid crystal display device, comprising: a liquid crystal display panel; and a liquid crystal driving device including first and second multi-channel thin film transistors wherein the first and second multi-channel thin film transistors respectively have an interval D between unit channels, a unit channel width W, and a unit channel length L, and wherein a W/L ratio of the first multi channel thin film transistor is larger than a W/L ratio of the second multi channel thin film transistor, and wherein an entire size of the first multi channel thin film transistors is larger than an entire size of the second multi channel thin film transistors when the first multi-channel thin film transistors have at least any one of a large interval D between each of unit channels and a small W/L ratio of the unit channel and the second multi-channel thin film transistors have at least any one of a small interval D between each of unit channels and a large W/L ratio of the unit channel, wherein the number of the unit channel of the first multi-channel thin film transistor is more than the number of the unit channel of the second multi-channel thin film transistor.
