PROBLEM TO BE SOLVED: To provide a data line drive circuit having a small wiring area and a high charge collection efficiency. SOLUTION: This data line drive circuit is provided with an S/H circuit, an R/W circuit, an output circuit, and a charge collection circuit 4 utilizing an L/C resonance circuit for switching connection of a column line collecting a panel voltage, and reusing it, and shares the voltage supply wiring of the output circuit in supplying and collecting charges, and the wiring is connected with the charge collection circuit 4 to change over the power supply and the charge collection route, and the switching of the column line is performed by an amplifying element constituting an output stage of the output circuit. Moreover, the shared wiring are divided into blocks of the odd numbered columns and the even numbered columns or those of red display columns, green display columns, and blue display columns.
