摘要:
A multilevel voltage generating circuit includes first and second input nodes provided on a first resistance element and supplied with first and second reference voltages. A current substantially flows in a first specific area for a line between the first and second input nodes based on a difference between the first and second reference voltages. A first group of output nodes are provided for the first resistance element to output a portion of a plurality of level voltages. A first one of the first group of output nodes for one of the plurality of level voltages which is closest to the first reference voltage is provided outside the first specific area. The first output node, the first input node, and the second input node, are arranged on a line on the first resistance element in this order.
