Abstract
A display panel, including first and second substrates assembled into a cell, a transparent medium provided therebetween, and charged light-absorbing particles mixed in the transparent medium. The first substrate includes a first base body and a total internal reflection structure, and a refractive index of the transparent medium is smaller than each of refractive indexes of the total internal reflection structure and the light-absorbing particles. Each pixel unit of the display panel is provided with plural electrode walls therein, the plural electrode walls in each pixel unit include first and second electrode walls. In a direction parallel to the display panel, the first electrode walls and the second electrode walls are provided alternately and wall surfaces thereof are opposite to each other, and electrode walls arranged opposite to each other are provided with a part of the total internal reflection structure therebetween.
