Abstract

To suppress malfunctions in a shift register circuit. A shift register having a plurality of flip-flop circuits is provided. The flip-flop circuit includes a transistor 11 , a transistor 12 , a transistor 13 , a transistor 14 , and a transistor 15 . When the transistor 13 or the transistor 14 is turned on in a non-selection period, the potential of a node A is set, so that the node A is prevented from entering into a floating state.

First claim

What is claimed is:

1. A driver circuit comprising:
a first transistor;
a second transistor;
a third transistor;
a fourth transistor;
a fifth transistor;
a sixth transistor;
