Abstract

The invention discloses a liquid crystal display device. The liquid crystal display device comprises a first substrate, a second substrate, a liquid crystal layer and an upper polaroid. The second substrate and the first substrate are oppositely arranged; the liquid crystal layer is arranged between the first substrate and the second substrate; the upper polaroid is arranged on the side, away from the liquid crystal layer, of the second substrate, the upper polaroid comprises a polarization layer and a color conversion layer, and the color conversion layer is located on the side, away from the liquid crystal layer, of the polarization layer. The contrast ratio of the liquid crystal display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] When a color conversion layer containing a color conversion material is set in a color filter substrate of a liquid crystal display (LCD), the down conversion fluorescent material is affected by the polarized light under the excitation of polarized light due to the influence of the fluorescence polarization characteristics The polarization state of the emitted light generated after excitation will change, resulting in light leakage in the dark state of the LCD, which greatly reduces the contrast of the LCD. Contents of the invention [0003] The embodiment of the present application provides a liquid crystal display device to solve the technical problem of lower contrast of LCD existing in the prior art. [0004] An embodiment of the present application provides a liquid crystal display device, which inc...
