Patent ID: 8625039

Claim:
A liquid crystal display device comprising a first substrate and a second substrate disposed to face each other so as to hold a liquid crystal layer between said first substrate and said second substrate, and a gate potential creating circuit for outputting a selection potential and a non-selection potential, scanning lines, signal lines, thin film transistors formed so as to correspond to intersection portions between said scanning lines and said signal lines, respectively, pixel electrodes electrically connected to said thin film transistors, respectively, and a gate control circuit for switching the selection potential and the non-selection potential supplied from said gate potential creating circuit over to each other, thereby supplying one of the selection potential and the non-selection potential to corresponding ones of said thin film transistors through corresponding one of said scanning lines being formed on said first substrate, and a common electrode being formed either on said first substrate or said second substrate, wherein a voltage control circuit for changing the non-selection potential to a potential in a rise area of said thin film transistor in accordance with a power source cut-off signal is connected between said gate potential creating circuit and said gate control circuit, said voltage control circuit includes a diode connected between a supply terminal for the non-selection potential of said gate potential creating circuit and a ground potential, a first switching element connected between said supply terminal for the non-selection potential of said gate potential creating circuit and an input terminal for the non-selection potential of said gate control circuit, and a short-circuit element connected between an input terminal for the selection potential and said input terminal for the non-selection potential of said gate control circuit, said first switching element cuts off between said supply terminal for the non-selection potential of said gate potential creating circuit and said input terminal for the non-selection potential of said gate control circuit in accordance with the power source cut-off signal, and said short-circuit element substantially short-circuits between said input terminal for the selection potential and said input terminal for the non-selection potential of said gate control circuit in accordance with the power source cut-off signal.
