<P>PROBLEM TO BE SOLVED: To provide a display panel, a display apparatus, a semiconductor integrated circuit and electronic equipment with high display quality in which a light emitting characteristic of each color is adjusted in appropriate relation and in which a digital to analog conversion characteristic of a D/A conversion circuit is stabilized, compared to when setting and supplying grayscale reference voltage are repeated during a light emitting period. <P>SOLUTION: A driving circuit for driving the display panel including a display area in which a subpixel as the minimum display unit is arranged in a matrix form, comprises; a group of digital to analog conversion circuits for converting a signal line data corresponding to each subpixel is converted into an analog value; a wiring pattern for giving a gray scale reference voltage to the group of digital to analog conversion circuit; and a sample and hold circuit which samples and holds the gray scale reference voltage corresponding to each color during a non-light emitting period of the display area and which apply the gray scale reference voltage to the corresponding wiring pattern during the light emitting period. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
