Abstract
The present invention provides a quantum dot display panel and a manufacturing method thereof. The quantum dot display panel includes a pixel layer having retaining walls and quantum dots, a lens layer having a lens array, and an enhancement film having a prism array. When ambient light enters the quantum dot display panel, it will be will be converged and collimated through the enhancement film, and focused onto the retaining walls with light absorption characteristics. The lens array maintains contrast of the quantum dot display panel, and the enhancement film enhances a display effect of wide viewing angle of the quantum dot display panel.
