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 liquid crystal display panel is provided, and includes a color film substrate and an array substrate. The array substrate includes a device layer disposed on a glass substrate; and two ultraviolet protective layers disposed on the same side of the device layer. A first ultraviolet protective layer is close to the UV light source, and a second ultraviolet protective layer is far away from the UV light source. The refractive index of the first ultraviolet protective layer to UV light is greater than the refractive index of the second ultraviolet protective layer to UV light. One UV mask is reduced, to ensure that device characteristics remain unaffected.

Abstract: The present invention provides a manufacturing method of a liquid crystal display (LCD) panel and the LCD panel. A thin film transistor (TFT) substrate and a color filter (CF) substrate are first bonded, a liquid crystal material is enclosed between the TFT and CF substrates to obtain a liquid crystal cell, which is then irradiated with ultraviolet light to obtain a functional liquid crystal layer, and finally a black matrix is formed on a side of the CF substrate away from the TFT substrate. By changing the structure of the existing LCD panel, the present invention prevents the shading of the black matrix that affects functional liquid crystal layer production. It is advantageous for a polymer liquid crystal technology, a self-aligned liquid crystal technology, and the like to realize a technique of forming a specific functional layer by irradiating the liquid crystal cell with ultraviolet light.
