The present application relates to the technical field of display, and discloses a display panel, a display apparatus and a display device. The display panel comprises a base substrate, a plurality of sub-pixels, a color filter layer, and a plurality of micro-lens structures. By providing the plurality of micro-lens structures, light having larger angles in light emitted by each sub-pixel can exit from a corresponding micro-lens structure, thereby improving the utilization rate of light emitted by the sub-pixels. Moreover, the axes of the micro-lens structures, the axes of transmitting areas of color resist blocks in the color filter layer, and the axes of the sub-pixels do not coincide, that is, the axes of the micro-lens structures and the axes of the transmitting areas of the color resist blocks in the color filter layer deviate from the axes of the sub-pixels; thus, light emitted by the sub-pixels can be prevented from exiting from the micro-lens structures corresponding to adjacent sub-pixels, the crosstalk between light emitted by adjacent sub-pixels is small, and the display effect of the display panel is good.

These devices may be used to form a dot-matrix display or an electronic information display comprised of a series of photopolymerizable, chiral liquid crystalline layers that can be solvent cast on a substrate. The mixture of chiral materials in each successive layer may be blended in such a way that each layer has the same chiral pitch and may also be blended so that the ordinary and extraordinary refractive indices in each layer match the other layers such that the complete assembly of layers will optically function as a single relatively thick layer or chiral liquid crystal. The chiral nematic material in each layer can spontaneously adopt a helical structure with a helical pitch. Further disclosed are pixel structures that not only emit light with brightness and chromaticity information, but also depth of focus information as well.
