Abrégé

The present disclosure discloses a display panel and a display device. The display panel includes an array substrate and a plurality of pixel units. In a first display area, a minimum distance between an edge of an anode of a second pixel unit and an edge of a corresponding light-emitting portion is greater than a minimum distance between an edge of an anode of a first pixel unit and an edge of a corresponding light-emitting portion. The display panel and the display device provided by the present disclosure prevents a problem that user experience is compromised by differences in brightness of the display panel at wide viewing angles.

Abrégé

Examples of the present disclosure disclose a display module and a terminal device. The display module includes a support layer, a backplane, and a display panel, wherein the display panel is disposed on one side of the backplane away from the support layer. The support layer includes a composite material layer which plays a supporting role, and the composite material layer includes at least a resin matrix and a fiber material. The weight of the support layer is reduced by preparing the composite material layer from a composite material with a density less than that of a SUS material.
