摘要： This disclosure provides novel latching circuits, and pixel circuits and display devices that include such latching circuits. The latches herein include a switch positioned on an inverter coupling interconnect which couples two cross-coupled inverters of the latch. The switch is configured to control a passage of a current between the first and second inverters. By switching the switch OFF at a time a data voltage is transferred to the inverters, any leak current between the inverters can be interrupted. As a result, a malfunctioning of the data latch is prevented.

In a display device which includes a display panel and a driving circuit on the same substrate, a booster circuit is formed on one side of a display panel together with the driving circuit and is formed by steps substantially equal to steps for pixel transistors. The booster circuit includes a circuit which compensates for the lowering of voltage of a switching element used in the booster circuit attributed to a threshold value of a switching element.
