The invention discloses a frame sealant. Warm-color liquid crystal micro-capsules are doped in the conventional frame sealant, the frame sealant which comprises the warm-color liquid crystal micro-capsules can be used for manufacturing a display part with a narrow frame, meanwhile, the warm-color liquid crystal micro-capsules can display different colors according to the temperature and meet requirements to attractiveness, the temperature of the display part can be monitored in real time according to the display color, and therefore, the circumstance that the display part is damaged due to over heat caused by running of the display part is avoided.
