Abstract

The invention provides a flexible substrate and a manufacturing method thereof and a flexible liquid crystal display panel. The manufacturing method of the flexible substrate is simple in manufacturing process, and the manufactured flexible substrate is provided with a plurality of transverse polymer retaining walls and a plurality of longitudinal polymer retaining walls. When the flexible substrate is applied to the flexible liquid crystal display panel, the transverse polymer retaining walls and the longitudinal polymer retaining walls can form a plurality of liquid crystal boxes between two opposite substrates in an enclosing mode, therefore, liquid crystal molecules can be contained in the liquid crystal boxes to prevent the liquid crystal molecules from flowing in a wide range, the display quality of the flexible liquid crystal display panel is improved, and the service life of the flexible liquid crystal display panel is prolonged; meanwhile, the polymer retaining walls can replace black matrixes to achieve the shading effect and also can replace spacers to achieve the effect of supporting the liquid crystal boxes.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible substrate, a manufacturing method thereof, and a flexible liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. Th...
