    Abstract: The present disclosure provides a display panel and a display device, which can reduce damage to a frame sealant caused by impact of a photoelectric material on the frame sealant during cell-assembling of the display. The display panel includes a first substrate, a second substrate, and a frame sealant and a photoelectric material layer between them; the photoelectric material is in a liquid and flowing status, the photoelectric material layer is located in and covers a display region of the display panel, and the frame sealant is located in a non-display region of the display panel. The display panel further includes a blocking portion provided in the non-display region and at a side of the frame sealant near the display region for blocking the photoelectric material. The blocking portion includes a channel for shunting the photoelectric material so as to block impact of the photoelectric material on the frame sealant.

    Abstract: The present disclosure provides a light guide plate-positioning column, a backlight module and a display apparatus. The column comprises a first positioning body for positioning a light guide plate and a second positioning body for positioning an optical film; the second positioning body is located on a side of the first and fixedly connected to it; a projection of the first positioning body in a direction from it toward the second completely covers that of the second, and a projection area of the first positioning body is greater than that of the second; wherein in the direction, a surface on a side of the first positioning body close to the second does not extend beyond a surface on a side of the plate close to the second. Both the requirements of the positioning strength of the plate and the fine positioning of the film can be met.
