Abstract: A display panel and a display device are provided. The resistance of a first equivalent resistor is set to be larger than the resistance of a second equivalent resistor so that voltage across the first equivalent resistor can be higher. In this way, when a second type of sub-pixel is driven to be lightened, and a first type of sub-pixel is driven not to be lightened, the first type of sub-pixel can be avoided from being lightened, due to the higher voltage across the first equivalent resistor despite leakages current, thus alleviating a display abnormality, and improving a display effect.
