Summary:Circuit of electrical level shifter possesses following parts and structures in order to execute stress test for circuit of selecting gray level effectively: electrical level supply wire 102, 101; PMOS 111, 121; NMOS 112, 122; wire 124 for connecting drain pole of NMOS 122 to gate of PMOS 111; wire 114 for connecting drain pole of NMOS 121 to gate of PMOS 121; wire 131, 132 for providing input signal IN, Inb for gate of NMOS 112, 122 respectively; wire 142 for outputting electric potential of drain pole of NMOS 112; wire 141 for outputting electric potential of drain pole of NMOS 122; and wirefor stress test. When gray level selection is in operation, different electric potentials of IN, Inb are output to the input wires of 131, 132 respectively, and the 141, 142 output wires output different electric potentials. In time of testing stress, the 141, 142 output wires output identical electric potential.
