Abstract
The present invention provides a liquid crystal display panel and a manufacturing method thereof. By mixing a spacer particle composite in a sealant, wherein temperature-responsive polymer vesicles comprise temperature-responsive polymer bodies and free radical inhibitors encapsulated by the temperature-responsive polymer bodies, and the temperature-responsive polymer vesicles release the free radical inhibitors at a default temperature, thereby preventing orientation dark lines or uneven peripheral brightnesses when the liquid crystal display panel displays.
Claims18
A liquid crystal display panel, comprising:
- a first substrate, a second substrate disposed opposite to the first substrate, a sealant disposed between the first substrate and the second substrate, and liquid crystal molecules disposed in a cavity surrounded by the first substrate, the second substrate, and the sealant;
- wherein temperature-responsive polymer vesicles are disposed within the sealant, the temperature-responsive polymer vesicles comprise temperature-responsive polymer bodies and free radical inhibitors encapsulated by the temperature-responsive polymer bodies, and the temperature-responsive polymer vesicles release the free radical inhibitors under a default temperature condition.
A manufacturing method of a liquid crystal display panel, comprising following steps of:
- coating a mixture of an adhesive and a spacer particle composite on a first substrate to form a frame-shaped sealant, wherein the spacer particle composite comprises spacer particles and temperature-responsive polymer vesicles, each of the temperature-responsive polymer vesicles is disposed on a surface of one of the spacer particles, the temperature-responsive polymer vesicles comprise temperature-responsive polymer bodies and free radical inhibitors encapsulated by the temperature-responsive polymer bodies, the temperature-responsive polymer vesicles release the free radical inhibitors under a default temperature condition, and the adhesive comprises a matrix resin, a photoinitiator, and a crosslinking agent;
- disposing a second substrate on the frame-shaped sealant to make the first substrate and the second substrate are disposed opposite with each other;
- irradiating the frame-shaped sealant with ultraviolet;
- and
- heating the frame-shaped sealant after an irradiation of the ultraviolet to 80 degrees Celsius to 130 degrees Celsius.
