Embodiment 1

[0046] Please refer to Figure 5 , wherein the LCD display panel 20 includes an upper substrate 200a (CF substrate), a lower substrate 200b (TFT array substrate), a sealant 220, a liquid crystal layer 230, a pressure-sensitive adhesive 240, an upper polarizer 210a, and a lower polarizer 210b, wherein The inner surface of the lower substrate 200b is provided with a sealant 220, and a liquid crystal layer 230 is arranged in the area surrounded by the sealant 220, and then the inner surface of the upper substrate 200a is bonded by the sealant 200, wherein the upper substrate 200a The two boards of the lower substrate 200b are arranged opposite to each other, so that the upper substrate 200a, the lower substrate 200b and the sealant 220 seal the liquid crystal layer 230 . Next, the upper polarizer 210 a is correspondingly attached to the outer surface of the upper substrate 200 a through the pressure-sensitive adhesive 240 , and the lower polarizer 210 b is correspondingly attache...

Embodiment 2

[0051] Since the initial development of LCD panel types, various technologies have been contending and changing with each passing day. However, from the perspective of the main direction of development, more is invested in the technology of wide viewing angle. Today, the horizontal steering drive of liquid crystal molecules is the best mode at present. There are currently two types of such modes, IPS and FFS, which are wide viewing angle technologies. Due to the uniqueness of positive horizontal driving, this type of LCD does not want to be disturbed by external electromagnetic fields, otherwise the effect of wide viewing angle will be greatly reduced. In this regard, the industry often adopts an additional backside indium tin oxide (Back side ITO) process to shield external interference electromagnetic fields. However, this increases the manufacturing cost accordingly

[0052] Please refer to Figure 6 , wherein the LCD display panel 30 includes an upper substrate 300a (CF...

Embodiment 3

[0057] With the development of modern technology, newer and better materials are gradually being developed. One of them is the self-assembled molecular film that has attracted much attention. Self-assembled molecular films (Self-assembled Monolayers, SAMs) are ordered supramolecular systems formed by the spontaneous adsorption of active molecules on the heterogeneous interface through chemical bonds. contact strength. After the film is formed, it can be transferred from the solution, which is an organic ultra-thin film technology that has attracted much attention at present. According to the difference between SAMs and the carrier, there are roughly the following chemical bonds: (1) organosilane derivatives are formed on the hydroxylated surface, such as Figure 7a Shown is the combination of a silicone derivative with a glass support. (2) Carboxylate compounds are formed on the surface of metal oxides, such as Figure 7b The indicated fatty acids (C n h 2n+1 COOH) and a...

Abstract

The invention provides a display panel which comprises an upper substrate and a lower substrate. The upper and lower substrates are oppositely arranged, more than one deboss is arranged on at least the outer side surfaces of the upper substrate and the lower substrate, a frame glue is located between two substrates to achieve a gluing effect, and a polaroid is at least attached to the outer surfaces of the upper substrate and / or the lower substrate. The display panel further comprises a filling and flattening layer which is located between the substrates and the Polaroid. The display panel has the advantages that by means of the arrangement of the filling and flattening layer, the problem that the polaroid is attached to bubbles caused by the deboss of the substrate surfaces is solved.

Description

【Technical field】 [0001] The invention relates to a flat panel display device, in particular to improving the attachment of polarizers and substrates in the manufacture of the flat panel display device, which can reduce the generation of attached bubbles. 【Background technique】 [0002] In recent decades, displays have developed rapidly. From the original cathode ray tube (Cathode Ray Tube, CRT), to the most common liquid crystal display (Liquid Crystal Display, LCD), and then to the forward-looking technology Organic Light-emitting Display (Organic Light-emitting Display, OLED) , obviously, flat-panel displays have become the leading development in the display field. From the perspective of the development of liquid crystal display, it has also gone through different technical stages: the initial Twisted Nematic (TN) liquid crystal display, compared with the traditional cathode ray tube (Cathode Ray Tube, CRT), has a low The advantage of energy consumption has gradually b...
