摘要：
The liquid jet recording head of this invention is configured such that the upper electrodes on a head substrate and the output terminals of a drive circuit using a thin film transistor are connected so as to face each other. P-channel thin film transistors are used in the analog switches in the drive circuit, and the piezoelectric device drive start timing is made to lag behind the timing with which the analog switches begin conducting.
