The liquid crystal display panel in this embodiment further includes a glass substrate layer, a brightness enhancement layer 10, and a diffusion layer 11, where the glass substrate layer and the first polarizing layer 2 are sequentially stacked in a first direction (the glass substrate layer is located above each blue light filtering layer), where a sixth blue light filtering layer is disposed on the upper surface of the glass substrate layer, or a seventh blue light filtering layer is disposed on the lower surface of the glass substrate layer (or a sixth blue light filtering layer is disposed on the upper surface of the glass substrate layer, and a seventh blue light filtering layer is disposed on the lower surface of the glass substrate layer). Wherein the sixth blue light-filtering layer is coated on the upper surface of the glass substrate layer by coating, and the seventh blue light-filtering layer is coated on the lower surface of the glass substrate layer by coating.
The brightness enhancement layer 10 and the diffusion layer 11 are both disposed between the second polarizing layer 8 and the backlight layer 9, and the second polarizing layer 8, the brightness enhancement layer 10, the diffusion layer 11, and the backlight layer 9 are sequentially stacked in the first direction (the diffusion layer 11 and the backlight layer 9 are both located below the blue light filtering layers). An eighth blue light filtering layer is arranged on the upper surface of the diffusion layer 11 and is coated on the upper surface of the diffusion layer 11 in a coating mode.
In this embodiment, the blue light filtering layer is disposed on the glass substrate layer and the diffusion layer 11, so that the liquid crystal display panel can further reduce the damage of blue light to eyes.
In another embodiment, an electronic device is further disclosed, and the electronic device includes any one of the liquid crystal display panels of the above embodiments. In this embodiment, electronic equipment such as a display, a mobile phone, a notebook computer, a television, etc. has a display product of a liquid crystal display panel, after the electronic equipment includes the above liquid crystal display panel, since the first polarizing layer 2 is provided with the first blue light filtering layer 1, and the second polarizing layer 8 is provided with the second blue light filtering layer 7, the first blue light filtering layer 1 and the second blue light filtering layer 7 filter sharp short-wave blue light in the blue light emitted by the liquid crystal layer 5, thereby reducing the damage of the blue light to eyes.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples are merely illustrative of several embodiments of the present application, which are described in more detail and detail, but are not to be construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
