Manufacturing method of flexible liquid crystal display panel

Abstract

The invention discloses a production method of a flexible liquid crystal display panel. Ultraviolet light is used to irradiate a liquid crystal box from a CF substrate, a color filter film of the CF substrate is utilized as a photomask, as a plurality of filter units which are formed on the color filter film corresponding to a plurality of sub-pixel areas have a shielding function to the ultraviolet light, under the irradiation of the ultraviolet light, reactive monomers mixed in liquid crystal materials correspondingly form a polymer wall in an area between a TFT (Thin Film Transistor) substrate and the CF substrate except for the plurality of sub-pixel areas, the polymer wall can surround liquid crystal molecules to prevent liquid crystal from flowing when the liquid crystal display panel is bent, so that the liquid crystal display panel can be maintained at a more uniform box thickness when being bent, the use of an additional photomask is saved, the production method is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible liquid crystal display panel. Background technique [0002] With the development of technology and social progress, flat displays can no longer meet people's needs, and some flexible displays are gradually entering people's lives. Organic light-emitting diode displays (organic light-emitting diode, OLED) have self-luminous, It has the characteristics of no backlight, thin thickness, wide viewing angle, fast response speed, etc., so it has the natural advantages of flexible display. However, its technical requirement threshold is high, the process technology is complicated, the yield rate is low, and the cost is high. These problems hinder the wide application of OLED. [0003] Liquid crystal display (Liquid Crystal Display, LCD) is currently the most widely used display product in the market. Its production process technology is very mature...

Problems solved by technology

like figure 2 As shown, since the liquid crystal material used in the liquid crystal panel is liquid and has fluidity, when the liquid crystal display panel is bent, due to the uneven force on the liquid crystal display panel in the bent state, the TFT substrate 120 and the CF substrate 110 The height of the columnar spacers 150 is different, so that the liquid crystal in the liquid crystal layer 130 is squeezed and flows, resulting in uneven thickness of the liquid crystal panel, so that the display of the liquid crystal display is uneven.
