Disclosed are a display panel and a display device. The display panel includes: a first substrate and a second substrate disposed as opposed to each other. The first substrate includes gate lines (1) and data lines (2), and pixel units (6) defined by the gate lines (1) and the data lines (2). The second substrate includes a black matrix (4), the black matrix (4) having a plurality of apertures (7) configured as corresponding to the pixel units (6). A orthographic projection of at least one side of at least a part of the plurality of apertures in a plane of the first substrate is at least partially located outside the pixel units (6).
