An ultraviolet (UV) curing apparatus for assembling the substrates comprises at least: a carrying means for holding the substrates, and the optical devices for providing UV light for the substrates. The optical devices at least comprise a back light unit (BLU) which is positioned at one side of the carrying means for even-illuminating UV light to the substrates. A light source and one light-guiding plate, or one lamp set and light-guiding plate assembly can be used in the back light unit of the invention, for improving the evenness of UV light illuminating from the light source or the lamp set to the substrates. Also, luminance can be greatly increased and the processing time is saved if UV spotlight is used as the light source. |
