Abstract: A display panel and a display terminal are disclosed. The display panel includes a display, a main board, and a FPC board connecting the display and the main board together. The FPC board has a portion of its surface attached with an EMI shielding layer. At least an edge of the EMI shielding layer is an edge with curves. The FPC board simplifies the assembly of the display panel, reduces production cost and maintenance inconvenience, and contributes to the display panel's downsizing. The EMI shielding layer prevents noises of different frequency ranges from affecting the display signals. The at least one edge with curves of the EMI shielding layer lessens stress between and therefore protects the EMI shielding layer and the FPC board from damages.
