Abstract

A panel module is provided, including a first substrate, a second substrate, a first optical glue, and a second optical glue. The first and second optical glues are disposed between the first and second substrates, wherein the first optical glue protrudes from the first substrate, and the second optical glue adheres the first substrate to the second substrate. Specifically, the viscosity of the second optical glue is smaller than the first optical glue before solidification.
