Problems solved by technology

[0002] The current LCD display devices basically use glass substrates as substrates. Display devices based on glass substrates cannot meet the designer's requirements for product shape in many cases due to their inability to bend. Moreover, glass substrates are generally thick, and are subject to pressure or impact. easy to break after
[0003] The traditional flexible LCD production process uses double-sided adhesive to attach the flexible conductive film to the glass substrate. However, the double-sided adhesive is generally only attached to the edge area of ​​the flexible conductive film, so that the middle area of ​​the flexible conductive adhesive cannot be completel

Abstract

The invention discloses a manufacturing method of a flexible liquid crystal display device. By bonding the whole surface of the flexible conductive film to the hard substrate by using the UV strippable adhesive film before the bonding process, the liquid can be prevented from entering between the flexible conductive film and the hard substrate in the process of contacting with the liquid, and theliquid crystal cell thickness is prevented from being uneven due to bulging in the middle of the flexible conductive film in the heating process; By arranging the spacer particles with viscosity between the upper and lower substrates, the problem of cell thickness unevenness caused by the movement of the spacer particles when the flexible liquid crystal display device is bent or twisted can be avoided, and the quality and service life of the flexible liquid crystal display device can be improved.

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 device. Background technique [0002] The current LCD display devices basically use glass substrates as substrates. Display devices based on glass substrates cannot meet the designer's requirements for product shape in many cases due to their inability to bend. Moreover, glass substrates are generally thick, and are subject to pressure or impact. easy to break after. [0003] The traditional flexible LCD production process uses double-sided adhesive to attach the flexible conductive film to the glass substrate. However, the double-sided adhesive is generally only attached to the edge area of ​​the flexible conductive film, so that the middle area of ​​the flexible conductive adhesive cannot be completely attached to the glass substrate. When they are bonded together, there will be moisture remaining between the flexib...
