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.

Abstract: A display panel and a display device are provided. The display panel includes an array substrate, an opposite substrate, and a liquid crystal layer between the array substrate and the opposite substrate. The array substrate is located above the opposite substrate near a light emerging side of the display panel. A photosensitive device is disposed inside the assay substrate, and a path for the photosensitive device to receive ambient light avoids a color resist layer in the display panel. The photosensitive device is not affected by the color resist layer when receiving infrared light from the outside, which can eliminate red spots on a display screen.
