The present high-frequency distribution circuit includes a switch circuit which passes a high-frequency signal from the other terminal of a high-frequency line to an output terminal if a receiver is connected to the output terminal and which grounds the other terminal of the high-frequency line via a terminator resistor if the receiver is not connected to the output terminal. Emulsion polymers included in the emulsions may have different glass transition temperatures. The thin film transistors are connected to the gate and data lines, and each thin film transistor includes a drain electrode.
