The invention provides a display panel. The display panel comprises a substrate; a plurality of pixel units arranged on the substrate, wherein each pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, and the second sub-pixel and/or the third sub-pixel includes a light conversion layer that converts light of one color into light of another color. The light conversion layer includes a nano-metal composite structure. The local surface plasmon polariton resonance effect of metal in the light conversion layer is utilized, so the intensity of fluorescence peaks in sub-pixels is enhanced, blue light peaks disappear, and the overall color gamut of the display panel is improved. 本发明提供了一种显示面板，包括：基板；设置于基板上的若干个像素单元，每个像素单元包括第一子像素，第二子像素和第三子像素；第二子像素和/或第三子像素包括光转换层，其将一种颜色的光转换为另一种颜色的光；光转换层包括纳米金属复合结构。本发明利用光转换层中金属的局域表面等离子体激元共振作用，子像素中荧光峰的强度增强，蓝光峰消失，显示面板的整体色域得到改善。
