## Abstract

The invention discloses a temperature regulation mask and an alignment layer pre-curing device, and is related to the field of manufacturing a liquid crystal display panel. Said temperature regulation mask is suitable for the alignment layer pre-curing device for pre-curing an alignment layer, and includes a base and a pattern arranged on the base. A pattern region of said temperature regulation mask has a different thermal conductivity from a thermal conductivity of a non-pattern region of said temperature regulation mask. A position of the one having a lower thermal conductivity among the pattern region and the non-pattern region of said temperature regulation mask corresponds to a position of said alignment layer corresponding to a metallic wiring region. The present invention can obtain an alignment layer with even thickness and improve a display quality.
