Abstract: A display panel includes a thin film transistor (TFT) array substrate, an opposite substrate, and a liquid crystal layer disposed between the TFT array substrate and the opposite substrate. The TFT array substrate includes a first substrate. The opposite substrate includes a second substrate. The display panel further includes a first viewing-angle improving layer disposed between the first substrate and the second substrate. The first viewing-angle improving layer adjoins one film layer on the first substrate or the second substrate. The first viewing-angle improving layer is disposed between the first substrate and the second substrate so that the first viewing-angle improving layer can be a stacked part manufactured integratedly with other film layers of the display panel. Thus, manufacture of the first viewing-angle improving layer can overcome a size limitation of a mold in a nanoimprinting technology, effectively improving a large-viewing-angle-display effect of a large-size display panel.
