A line driver circuit, an electro-optic device, and a display apparatus efficiently reduce cost by reducing process dimensions and effectively shorten display panel development turn-around time. A signal driver 30 for display an LCD panel of a liquid crystal display apparatus has an input terminal group 282 containing a I/O circuit area 280 to which an input signal group is input, and a output terminal group 284 from which an output signal group is output. The I/O circuit area 280 includes a phase inversion circuit 286 for phase inverting an input signal group input through the input terminal group 282, and a level shifter 288 for converting low voltage resistance voltages of the signal group phase inverted by the phase inversion circuit 286 to a high voltage resistance voltage. The input terminal group 282 and output terminal group 284 can be freely selected from plural terminal groups in the signal driver 30.
