Abstract
An electronic device includes pixel regions and pixel spacing regions, and includes: a display layer disposed in the pixel regions and the pixel spacing regions, and including a liquid crystal material and a dye material; and reflective layers respectively disposed in the pixel regions, and at one side of the display layer. The display layer is in a scattering state under a non-display state, and light is scattered by the liquid crystal material and absorbed by the dye material when the light passes through the display layer. The display layer in the pixel regions is in a transmissive state and the display layer in the pixel spacing regions is in a scattering state under a display state, and light passes through the liquid crystal material and the dye material in the pixel regions and is reflected by the reflective layers when the light passes through the display layer.
