Abstract: The present invention provides a backlight module and a display device. The present invention splices a substrate on a reflection plate. The reflection layer can effectively replace the reflection plate in function because of a high reflectivity of the reflection layer on the spliced portion between the substrate and the reflection plate, which guarantees extension of light and lowers requirement for assembling precision.

Abstract: The technical field of liquid crystal display panels is related to, and an in-cell touch panel is provided. The in-cell touch panel includes a first substrate, a conductive line, an alignment film, a spacer, and a second substrate sequentially from bottom to top, and further includes a black matrix covering the conductive line. Without changing a total contact area between a first contact surface of the spacer and the conductive line, the spacer can be arranged to completely stand on the conductive line by changing a shape of the first contact surface. When the panel is made thinner or is pressed, contact and friction between the spacer and the alignment film around the conductive line can be avoided, and large-area non-uniform liquid crystal alignment can be avoided. An area of the black matrix arranged around the spacer can be greatly reduced, and accordingly an aperture ratio of pixels can be improved.
