Abstract: A method of grinding a substrate is provided. A substrate including a first main surface having a semiconductor layer formed thereon and a second main surface opposed to the first main surface is prepared. A support film is attached to the first main surface using a glue. The second main surface of the substrate is ground so as to reduce a thickness of the substrate. The support film is removed from the first main surface by applying force to the support film in a non-traverse direction.

Abstract: A display driving device includes a power circuit, a gate driver, a data driver, and a controller. The power circuit generates gate supply voltages. The gate driver applies a gate driving signal to gate lines. The data driver applies data signals to data lines intersecting the gate lines. The controller controls the power circuit, the gate driver, and the data driver to set the gate driving signal to be at least one of the gate supply voltages when abnormal power off occurs. The controller also controls the power circuit to allow the gate supply voltages to be discharged naturally.
