Abstract:
1. 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 ratios 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; and wherein 0.5 μm≦the unit channel width W of the first and second multi-channel thin film transistors≦1000 μm, 0.5 μm≦the interval D between the unit channels of the first multi-channel thin film transistor≦500 μm, and 0.25 μm≦the interval D between the unit channels of the second multi-channel thin film transistor≦125 μm.
