Problems solved by technology
At present, polyimide (PI) is widely used as a flexible substrate in the production process of flexible liquid crystal display panels, but due to the absorption of UV light by PI at present, see for example figure 1 , figure 1 It is the ultraviolet absorption spectrum of visible light-curable polyimide in the prior art. In the traditional process of using ultraviolet light to cure the sealant, the ultraviolet light of 300nm to 400nm is absorbed by the flexible substrate, which will cause the sealant of the flexible liquid crystal display panel Abnormal curing occurs, affecting the quality of the product, and even causing product failure

Abstract
The invention discloses a display panel. The display panel comprises a first substrate and an opposite substrate which are oppositely arranged, and further comprises a frame glue arranged between thefirst substrate and the opposite substrate and forming a sealed cavity together with the first substrate and the opposite substrate, a fluorescent material is arranged in at least one of the first substrate, the opposite substrate and the frame glue, and the fluorescent material emits second light under the excitation of first light; the wavelength of the first light is 147 nm or 234 nm, and the wavelength of the second light is 365 nm to 380 nm; and the frame glue can be cured by the second light.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the rapid development of liquid crystal display technology, liquid crystal display panels (LCD) will also develop from straight to flexible. Flexible liquid crystal display panels are formed by precise polymer space walls (Polymer Space Walls) to stabilize the liquid crystal when it is flexed. State and cell thickness (Cell Gap). At present, polyimide (PI) is widely used as a flexible substrate in the production process of flexible liquid crystal display panels, but due to the absorption of UV light by PI at present, see for example figure 1 , figure 1 It is the ultraviolet absorption spectrum of visible light-curable polyimide in the prior art. In the traditional process of using ultraviolet light to cure the sealant, the ultraviolet light of 300nm to 400nm is absorbed by the flex...
