Abstract
A display panel and a display device are provided. A sub-pixel unit of the display panel includes at least one light-transmitting region, and each light-transmitting region is provided with at least one driving transistor. At least part of a source wiring of the driving transistor is disposed at a boundary of the light-transmitting region and parallel to an extension direction of data signal lines, and a drain wiring is disposed in the light-transmitting region. The light-transmitting region of the sub-pixel unit occupied by the driving transistor is reduced to alleviate a problem of low aperture ratio of a backplane of current display products.
Claims16
A display panel, comprising:
- gate scan lines extending along a first direction;
- and
- data signal lines extending along a second direction, wherein the data signal lines intersect the gate scan lines to define a plurality of sub-pixel units, each of the sub-pixel units comprises at least one light-transmitting region, each of the at least one light-transmitting regions is provided with at least one driving transistor, and the driving transistor comprises a source wiring and a drain wiring;
- and
- wherein at least part of the source wiring of the driving transistor is disposed at a boundary of the at least one light-transmitting region and parallel to an extension direction of the data signal lines, and the drain wiring is disposed in the at least one light-transmitting region,
