Abstract

The invention discloses a color film substrate, a manufacturing method thereof and a display panel. The color film substrate is sequentially provided with a first substrate, a color resistance layer,a flat layer and a quantum dot layer in a stacked mode in the first direction. The color resistance layer is provided with a plurality of sub-color resistance layers with different colors along a second direction, and a black matrix is not arranged between every two adjacent sub-color resistance layers; the quantum dot layer is divided into a plurality of quantum dot areas in the second direction,a dike part is arranged between every two adjacent quantum dot areas, the dike parts are right opposite to every two adjacent color resistance layers, and the color of the dike parts is black. According to the invention, the light loss in the display panel is reduced, and meanwhile, the technical difficulties and the manufacturing cost are also reduced; furthermore, the dike parts are arranged between every two adjacent quantum dot areas, the dike parts are black, light leakage between the light-emitting areas can be prevented, the preset length of the dike parts in the first direction is thefirst length L, the preset length range of the first length L is that L is larger than 6 micrometers, and the thickness printing requirement of the quantum dot layer is met.

Description

technical field [0001] The present application relates to the display field, in particular to a color filter substrate, a manufacturing method thereof, and a display panel. Background technique [0002] With the development of the panel display industry, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) panel manufacturing technology will move towards lower cost and higher luminous efficiency. Generally, adding some quantum dots to the OLED display panel can improve the light output efficiency of the OLED display panel. Quantum dot printing technology has become the technical direction pursued by many companies in the industry because of its high ink material utilization rate and high luminous efficiency. [0003] At present, the design of the color film in OLED generally refers to the color film structure in the LCD (Liquid Crystal Display, liquid crystal display panel), and the color film layer involved in the LCD is generally formed on the package cover, i...
