    Abstract: A display including a first substrate, a first electrochromic layer, a light emitting layer, a second electrochromic layer and a second substrate that are sequentially stacked are provided. A display area of the display panel includes a plurality of sub-pixels arranged in an array, the first electrochromic layer includes a plurality of first sub-electrochromic layers corresponding to the plurality of sub-pixels, and the second electrochromic layer includes a plurality of second sub-electrochromic layers corresponding to the plurality of sub-pixels, each first sub-electrochromic layer and each second sub-electrochromic layer are configured to switch between a light-transmissive state and a light-shielding state in response to an external voltage. The display panel can switch between a double-sided display state and a single-sided display state, meanwhile a phenomenon of mirror images can be avoided in case of double-sided display state.
