Active matrix type display device

Abstract

Abstract PURPOSE: To obtain normal display regardless of a production defect in a partial data signal write route by providing plural data signal write routes to a display element. CONSTITUTION: For example, if a scanning line G1 gets defective and field effect transistors FETs T11A, T12A, T21A, and T22A connected to the scanning line G1 come into the normally turned-off state, only FETs T11B and T12B are turned on in odd frames, and a normal data signal is written in display elements C11 and C12. Only FETs T21B and T22B are turned on in even frames, and the normal data signal is written in display elements C11 and C12. Then, the data signal written in display elements for the period of two frames is held, and the normal data signal is written once in two frames, thus obtaining the normal picture display.
