PURPOSE: A source IC(Integrated Circuit) having multi output per channel and LCD(Liquid Crystal Display) is provided to reduce an output unit number of a source driver by having output units as much as resolution by realizing a multi output through one output unit. CONSTITUTION: A source driver IC(Integrated circuit)(300) comprises a both direction shift register unit(310), a data register unit(320), a latch unit(320), a level shift unit(340), a DAC(digital to analog convertor)(350), and an output unit(360). The both direction shift register unit(310) is inputted an outer power source voltage(Vdd), an operating voltage of a system(Vss) from the outer and a clock signal(CLK) from a timing control unit(100). In the status of the both direction shift register unit(310) starts the driving when a high level signal of DI01 is inputted, sequentially shifts a pulse signal from the left to the right, and transmits the pulse output to other source driver IC(Integrated Circuit)(320) connected to the right unit with a DI02.
