Abstract: The present application provides a liquid crystal display panel and a manufacturing thereof. The liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, and support posts. Each of the support posts includes a support post body and an expandable auxiliary pad. In a first state, the auxiliary pad is in a non-expanded state, and in a second state, the auxiliary pad is in an expanded state. This compensates for a height difference caused by the support post body which cannot be restored after being compressed by an external force and relieves a problem of appearance of Mura in the liquid crystal display panel.

Abstract: The disclosure provides a liquid crystal display (LCD) device and a manufacturing method thereof. A temperature sensing driver chip is disposed in the LCD device and can output a voltage signal to a control electrode according to changes in temperature. Therefore, an electric field is formed between the control electrode and a common electrode. Heights of a plurality of supporting posts can be changed by the electric field to control stretching and shrinking of the control electrode, thereby improving performance of the supporting posts. Thus, a plurality of organic material spheres disposed in the supporting posts can improve stress tolerance of the supporting posts, thereby further improving performance of the supporting posts.

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.
