  • Patent number: 10591779
    Abstract: A display panel and a display device are provided. The display panel comprises a first substrate (1) and a second substrate (2) provided opposite to each other, and a spacer (101) provided between the first substrate (1) and the second substrate (2). The spacer (101) is covered with an alignment film (4), both the first substrate (1) and the second substrate (2) includes an active display region (102) and a non-display region (103), the spacer (101) is provided in the non-display region (103) of the first substrate (1) and the non-display region (103) of the second substrate (2). A minimum distance value from an edge of the spacer (101), which is an edge closest to the active display region (102) along a rubbing direction of the alignment film (4), to the active display region (102) along the rubbing direction of the alignment film (4) is within a preset range for avoiding light leakage caused by the spacer.
