Fig. 5 is a partial cross-sectional view of a non-display region of the liquid crystal display device of fig. 1. Referring to fig. 5, the black matrix 10 has at least one first through hole 11 for passing ultraviolet light in the first non-display area 102 of the color filter substrate 100, and the peripheral metal circuit has at least one second through hole 21 for passing ultraviolet light. In this embodiment, the first through hole 11 and the second through hole 21 are both long strips, for example. In order to prevent the non-display area of the liquid crystal display device from transmitting light, the projection of the at least one first through hole 11 on the array substrate 200 is completely non-overlapped with the at least one second through hole 21.
Further, to prevent the non-display area of the lcd device from transmitting light, the projection of the at least one first through hole 11 on the array substrate 200 is covered by the opaque area of the array substrate 200, and the projection of the at least one second through hole 21 on the color filter substrate 100 is covered by the opaque area of the color filter substrate 100.
