Abstract

The invention provides a quantum dot color film substrate and a liquid crystal display device. The liquid crystal display device comprises a quantum dot color film substrate, comprising a substrate, acolor filter layer, a band-pass filter film and a packaging layer; an array substrate disposed opposite to the quantum dot color film substrate; a liquid crystal layer disposed between the quantum dot color film substrate and the array substrate; and a backlight module, disposed below the array substrate.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a quantum dot color film substrate and a liquid crystal display device. 【Background technique】 [0002] A quantum dot (quantum dot, QD) is a nanoparticle composed of II-VI or III-V elements, which can emit fluorescence after being excited, and its luminescence spectrum can be controlled by changing the size of the quantum dot. Good strength and stability. [0003] At present, there is a quantum dot color film liquid crystal display device designed with an in-cell polarizer, and the configuration of the quantum dot color film is different from that of the traditional quantum dot color film liquid crystal display device. In this design, the quantum dot color resistance is packaged on the upper surface of the color filter substrate, so the metal wire grid polarizer can be arranged on the lower surface of the color filter substrate. Because the metal wire grid has a nanoscale st...
