PROBLEM TO BE SOLVED: To provide a voltage level conversion circuit with a stable transition delay characteristic. SOLUTION: A voltage level conversion circuit changes an input signal of a first voltage into an output signal of a second voltage. The circuit includes an input terminal receiving an input signal, an output terminal outputting an output terminal, and first and second level-shifting units connected in parallel between the input and the output terminals. In particular, the first and the second level-shifting units have difference transition delay characteristics, enabling rising and falling transition delays to be variable in the same ratio when the first and the second voltages are changed.
