Abstract
The present application provides a display panel and a manufacturing method of the display panel. When an electrochromic layer is completely closed, a metasurface structure and an electrowetting structure reflect a light with corresponding wavelength to form a reflection state. When the electrochromic layer is partially closed, the metasurface structure and the electrowetting structure corresponding to a part of the closed electrochromic layer reflect the light with corresponding wavelength to form the reflection state, and the light penetrates through the wetted metasurface structure and a part of the unclosed electrochromic layer to form a transparent state.
