A source driving circuit includes a first source channel configured to output a first source driving signal to a display panel; a second source channel configured to output a second source driving signal to the display panel; a first gamma circuit configured to output first gamma values to the first source channel; and a second gamma circuit configured to output second gamma values to the second source channel. The first gamma circuit may set the first gamma values to values corresponding to red or green depending on a first switching operation of a first demultiplexer of the display panel corresponding to the first source channel. The second gamma circuit may set the second gamma values to values corresponding to blue or green depending on a second switching operation of a second demultiplexer of the display panel corresponding to the second source channel.
