Voltage level shifter and display device

A display device having:

• a matrix having elements corresponding to pixels of the display;
• at least one driver connected to the matrix to drive the matrix;
• an input device for receiving external input signals via input terminals, the input device being connected to the at least one driver for outputting level shifted signals;
• and
• wherein the input device comprises a voltage level shifter, said voltage level shifter including:
• first to fourth transistors, where the first to fourth transistors are P-type transistors,
• the first and second transistors being connected in series between first and second power supply inputs with the control electrode of the second transistor being connected to a first input for receiving a direct input signal,
• the third and fourth transistors being connected in series between the first and second power supply inputs with the control electrode of the fourth transistor being connected to a second input for receiving a complementary input signal,
• the control electrode of the first transistor being connected to the output electrode of the third transistor and the common electrode of the fourth transistor, and
• the control electrode of the third transistor being connected to the output electrode of the first transistor and the common electrode of the second transistor.
