Ultraviolet light curing mask plate and manufacturing method and curing method therefor

Abstract

The invention provides an ultraviolet light curing mask plate and a manufacturing method and a curing method therefor. The ultraviolet light curing mask plate comprises a mask plate substrate; a blocking region and a light-transmitting region are arranged on the mask plate substrate; the blocking region is corresponding to a liquid crystal region of a liquid crystal display panel; the light-transmitting region is corresponding to a region wherein a sealant of the outer frame of the liquid crystal display panel is located; the light-transmitting region allows ultraviolet light to penetrate through; at least one light path changing apparatus is arranged in the light-transmitting region; and the light path changing apparatus can change the light path of ultraviolet light. The ultraviolet light curing mask plate has the advantages as follows: the light path changing apparatus is added to the ultraviolet light curing mask plate, so that the ultraviolet light which perpendicularly irradiates to the ultraviolet light curing mask plate can irradiate the region, covered with metal lines, of the liquid crystal display panel completely and uniformly, thereby fully curing the sealant and avoiding puncture risk.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an ultraviolet curing mask plate, a manufacturing method and a curing method thereof. Background technique [0002] With the rapid development of the thin film transistor liquid crystal display (TFT-LCD, Thin Film Transistor Liquid Crystal Display) industry, liquid crystal display panels are developing toward high precision and more intensive integration, such as GOA products. [0003] figure 1 It is a structural schematic diagram of a liquid crystal display panel of an existing thin film transistor liquid crystal display device. see figure 1 Generally, a liquid crystal display panel of a thin film transistor liquid crystal display device is composed of a color filter substrate (CF, Color Filter) 10, a thin film transistor substrate (TFT, Thin Film Transistor) 11, and a film sandwiched between the color filter substrate 10 and the thin film transistor substrate 11.

Problems solved by technology

However, the above method has the following disadvantages: as more and more peripheral circuits are integrated on the thin film transistor substrate, it will inevitably lead to extremely dense metal wires in the outer frame glue area of ​​the thin film transistor substrate, and these metal wires will affect the UV curing of the frame glue. Light has a certain blocking and reflection effect, which affects the curing of the frame glue. In severe cases, it can lead to poor curing of the frame glue and cause punctures.
