Abstract: A manufacturing method for a liquid crystal display panel is disclosed and includes a step forming a refractive index gradient layer, a step forming a gate electrode insulation layer, a step forming a first interlayer dielectric layer, and a step forming a second interlayer dielectric layer. The step forming a refractive index gradient layer includes depositing a silicon nitride layer on a glass substrate, depositing the refractive index gradient layer on the silicon nitride layer. The refractive index gradient layer is silicon oxide, and includes a lower refractive index decremental layer and a lower refractive index constant layer. A refractive index of the decremental layer gradually decreases along a direction away from the silicon nitride layer, the lower refractive index constant layer is on the lower refractive index decremental layer. A reflection rate between light in film layers can be lowered to improve light transmittance of the display panel.
