Title:
DRIVE CIRCUIT FOR DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/190187
Kind Code:
A1
Abstract:
A drive circuit for a display device includes a TFT having a source electrode 15, a drain electrode 14, and a gate electrode 13. An electrically isolated light shielding film 12 is provided, which has a main part for shielding a channel part of the TFT from light and an extension part 20 integrally formed with the main part. An auxiliary capacitance C2 is formed with the extension part 20 and an electrode member 21 integrally formed with the source electrode 15, arranged so as to appear stacked in a plan view. The electrode member 21 may be replaced by an electrode member formed in the same layer as the channel part and connected to the source electrode 15, an electrode member connected to one conduction electrode in another TFT, or an electrode member integrally formed with the gate electrode 13. Thereby, a drive circuit with a small area, including a light-shielded thin film transistor, is provided at a low cost.
