摘要： The present disclosure relates to a display electronic slurry (DES) panel, including an upper substrate, a lower substrate, and a DES cavity between the upper substrate and the lower substrate. A filter layer is disposed on a surface of the upper substrate facing the lower substrate, and a pixel electrode layer is disposed on a surface of the lower substrate facing the upper substrate. The DES cavity is provided with a support structure; an indium tin oxide (ITO) film is disposed between the support structure and the filter layer. A lower surface of the ITO film is in contact with an upper surface of the support structure, and a lower surface of the support structure is in contact with an upper surface of the pixel electrode layer. The filter layer includes a plurality of color filters, an optical coating (OC) layer is disposed between gaps of the color filters, and the filter layer is attached to an upper surface of the ITO film by using an optically clear adhesive (OCA) layer. In the DES panel in the present disclosure, one OC layer is coated between the gaps of the color filters to achieve a smooth surface of the upper substrate, and the ITO film is attached by using OCA to achieve a uniform electric field between the upper and lower substrates of the DES panel, improve a refresh life and a contrast of the DES panel, reduce diffraction, increase color saturation of the DES panel, and improve pressure resistance of the DES panel.
