Patent ID: 11408586

Abstract:
The present invention provides a display device including a display panel, a backlight module, and a microstructure layer. The microstructure layer has a base layer and a plurality of microstructure groups. Each microstructure group includes: a central structure with a central trapezoidal section, a first structure with a first trapezoidal section, and a second structure with a second trapezoidal section arranged on a second side of the central structure. Based on the height of the central trapezoidal section, the legs of the first trapezoidal section and the second trapezoidal section facing away from the central structure are more inclined than the legs of the first trapezoidal section and the second trapezoidal section toward the central structure. The longer baselines of the central trapezoidal section, the first trapezoidal section, and the second trapezoidal section are all closer to the backlight module than the shorter upperlines.
