Abstract: A liquid crystal display device and an electronic equipment are provided. The liquid crystal display device includes a liquid crystal display panel and an adjustable diffusion sheet configured to improve a light transmissive rate of a light transmissive region. The adjustable diffusion sheet includes a first sub-section corresponding to the position of the light transmissive region. When the light transmissive region is in a transparent state, the first sub-section is in a transparent state. When the light transmissive region is in a display state, the first sub-section is in a fog state.

Abstract: A display panel is provided. The display panel comprises a display screen, a first backlight module, a second backlight module, and a fingerprint sensor, wherein the second backlight module has a fingerprint identification mode and a display mode. In the fingerprint identification mode, light reaches the fingerprint sensor through the second backlight module for fingerprint identification, and in the display mode, the first backlight module and the second backlight module provide uniform backlight to the display screen, thus realizing compatibility of functions of under-screen fingerprint identification and display.
