Abstract

A reference voltage circuit, a reference voltage supply main circuit and a display device are provided. The reference voltage circuit includes N first voltage lines and M second voltage lines configured to receive first and second voltages, respectively, and a resistance circuit including M resistors. A m-th resistor includes P first sub-resistors, and first and second terminals of a p-th one of the first sub-resistors is connected to a p-th one of the first voltage lines and a m-th one of the second voltage lines; a resistance value of each first sub-resistor is larger than that of each first voltage line, P is a positive integer smaller than or equal to N, m is a positive integer smaller than or equal to M, and p is a positive integer smaller than or equal to P.
