Abstract
Provided are a backlight module and a liquid crystal display device. The backlight module includes: a backlight source structure layer; and a first convex lens structure layer, a second convex lens structure layer and a prism layer that are sequentially arranged at a light-emergent side of the backlight source structure layer. The parallel lights emitted from the backlight source structure layer are converged to a focal point of the second convex lens structure layer after passing through the first convex lens structure layer, and transformed into the parallel light beam after passing through the second convex lens structure layer. The parallel lights are transformed to parallel light beam in a convergence state from an original well-distributed state. The parallel light beam is refracted for multiple times after passing through the prism layer to realize light splitting, so that lights with different colors are refracted.
