Title:
SHIFT REGISTER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2016/190186
Kind Code:
A1
Abstract:
Provided is a shift register circuit allowing malfunctions due to a threshold shift in a thin-film transistor caused by external light to be prevented. A unit circuit constituting each stage of a shift register circuit includes a plurality of thin-film transistors. The plurality of thin-film transistors is classified into a first group (T2, T4, T9) in which the on and off states are controlled by a relatively high on-duty, and a second group (T1, T3, T5, T6, T7, T8) in which the on and off states are controlled by a relatively low on-duty. In this configuration, a light shielding film (LS) is provided only on a thin-film transistor included in either the first group or the second group.
