Abstract
The present invention discloses a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate and a second substrate. A first underlay substrate of the first substrate is disposed with an optical sensor. Sensing transistors of the optical sensor includes a first semiconductor. A color filter layer is disposed between the first semiconductor and the first underlay substrate. The color filter layer includes color resist blocks and a light shielding portion. an orthographic projection of the light shielding portion on the first underlay substrate covers an orthographic projection of the first semiconductor on the first underlay substrate.
