The display panel includes: a backlight module including a light-exiting side; and a display module including: a liquid crystal panel disposed on the light-exiting side of the backlight module, a surface glass attached to a surface of the liquid crystal panel away from the backlight module, and a front frame component disposed around the display module and fixing the display module to the backlight module. ## Claims ### Claim 1 A display panel, comprising: a backlight module comprising a light-exiting side and an outer frame; and a display module comprising: a liquid crystal panel disposed on the light-exiting side of the backlight module, a surface glass attached to a surface of the liquid crystal panel away from the backlight module, and a front frame component disposed around the display module and fixing the display module to the backlight module, wherein the front frame component comprises four frames connected end to end, and the frame comprises: a first frame body having a first end and a second end, a second frame body vertically connected to a surface of the first end near the display module, and a third frame body vertically connected to a surface of the second end away from the display module; wherein the outer frame of the backlight module comprises: a first connection portion disposed on a side of the first frame body near the display module and parallel to the first frame body, a second connection portion disposed on a side of the third frame body away from the display module and parallel to the first frame body, and a third connection portion connected between the first connection portion and the second connection portion and parallel to the third frame body; wherein the third frame body of the frame comprises an upper threaded hole, the third connection portion comprises a lower threaded hole corresponding to the upper threaded hole, and the third frame body is fixedly connected to the third connection portion of the outer frame by a screw penetrating the upper threaded hole and the lower threaded hole. ### Claim 2 (depends on 1) The display panel as claimed in claim 1, wherein the surface glass attached to the surface of the liquid crystal panel away from the backlight module through a full lamination process. ### Claim 3 (depends on 1) The display panel as claimed in claim 1, wherein the display module is adhered and fixed on the second frame body of the front frame component by a double-sided adhesive. ### Claim 4 (depends on 3) The display panel as claimed in claim 3, wherein the double-sided adhesive is disposed on a surface of the second frame body away from the backlight module. ### Claim 5 (depends on 1) The display panel as claimed in claim 1, wherein the backlight module comprises a light guide plate surrounded by the outer frame and a light source disposed between the light guide plate and the outer frame. ### Claim 6 (depends on 1) A display device, comprising a display panel as claimed in claim 1, wherein the display panel comprises: a backlight module comprising a light-exiting side and an outer frame; and a display module comprising: a liquid crystal panel disposed on the light-exiting side of the backlight module, a surface glass attached to a surface of the liquid crystal panel away from the backlight module, and a front frame component disposed around the display module and fixing the display module to the backlight module, wherein the front frame component comprises four frames connected end to end, and the frame comprises: a first frame body having a first end and a second end, a second frame body vertically connected to a surface of the first end near the display module, and a third frame body vertically connected to a surface of the second end away from the display module; wherein the outer frame of the backlight module comprises: a first connection portion disposed on a side of the first frame body near the display module and parallel to the first frame body, a second connection portion disposed on a side of the third frame body away from the display module and parallel to the first frame body, and a third connection portion connected between the first connection portion and the second connection portion and parallel to the third frame body; wherein the third frame body of the frame comprises an upper threaded hole, the third connection portion comprises a lower threaded hole corresponding to the upper threaded hole, and the third frame body is fixedly connected to the third connection portion of the outer frame by a screw penetrating the upper threaded hole and the lower threaded hole. ### Claim 7 (depends on 6) The display device as claimed in claim 6, wherein the surface glass attached to the surface of the liquid crystal panel away from the backlight module through a full lamination process. ### Claim 8 (depends on 6) The display device as claimed in claim 6, wherein the display module is adhered and fixed on the second frame body of the front frame component by a double-sided adhesive. ### Claim 9 (depends on 8) The display device as claimed in claim 8, wherein the double-sided adhesive is disposed on a surface of the second frame body away from the backlight module. ### Claim 10 (depends on 6) The display device as claimed in claim 6, wherein the backlight module comprises a light guide plate surrounded by the outer frame and a light source disposed between the light guide plate and the outer frame.
