Abstract: The disclosure provides a display panel and a display device. In an array substrate of the display panel, at least two protrusions are defined on a side of a non-display region away from a display region to form an extending portion. A recess is defined between adjacent protrusions. A driver chip is disposed in a space between a periphery of a display region and a periphery of a non-display region. Distances between the driver chip, the periphery of the display region, and the periphery of the non-display region are increased. A bending section of a flexible circuit board is disposed in the recess. As a result, width of the non-display region will not be increased.

Abstract: A thin film transistor and a display panel are provided. A first dimension of a first transmission portion electrically connected to a source heavily-doped portion is different from a second dimension of a second transmission portion electrically connected to a drain heavily-doped portion, so that an intensity of an electric field of carriers transmitted by the transmission portion corresponding to the larger one of the first dimension or the second dimension is smaller when the thin film transistor is turned on, thereby reducing the bombardment effect of the carriers on a source or a drain and improving the stability of thin film transistor.
