Description

TECHNICAL FIELD [0001] The present invention relates to a transparent substrate surface treatment method and a display device including a surface-treated transparent substrate.

The present invention relates to a surface treatment method of a transparent substrate, and more particularly to a surface treatment method of a transparent substrate capable of low reflection and contamination by treating a transparent substrate using fluorine-based polymer nanoparticles, .

2. Description of the Related Art In recent years, various portable electronic devices such as a mobile phone, a PDA, and a notebook computer have been developed, and thus there is a growing need for a flat panel display device for a light and small-sized flat panel display device. Various flat panel display devices such as a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting display, and an electrophoretic display device have been proposed as flat panel display devices.

In such a flat panel display device, a thin film transistor, various electrode wirings, and a color filter layer are formed on a transparent glass substrate, and a liquid crystal layer, an electrophoretic layer, a plasma layer or an organic light emitting layer is formed between the substrates, So that an image can be realized.

However, when light is incident on the upper surface of the glass substrate from the outside when the user uses such a display element, the visibility of the display element is lowered due to reflection of the glass substrate. Particularly, although the flat panel display device is used indoors as well, it is often used outdoors, so that visibility deteriorates due to reflection of strong external light.

In order to solve such a problem, a method of treating a glass substrate to reduce reflectance has been studied recently. Currently, such glass substrate processing includes a method of coating a reflection reducing material such as MgF with a single layer, and a method of coating SiO ₂ and TiO ₂ by coating multiple layers. The transmittance of the visible light ray is improved from 92% to 98% or more by the surface treatment process of the glass substrate by the reflection reducing material, and as a result, resolution and clarity are improved.

However, the above-mentioned substrate processing by the low reflection material has the following problems.

Although the substrate treatment using MgF is coated with a MgF layer as a single layer, the reflectance is reduced due to the refractive index difference between glass and MgF. However, in the method of coating MgF, there is a problem that the reflectance depending on the wavelength is different due to the change of the refractive index depending on the wavelength of the light of MgF.

In addition, SiO ₂ and TiO ₂ are formed in multilayers and the surface of the substrate is treated by alternately depositing SiO ₂ having a refractive index and TiO ₂ having a high refractive index to form multi-layers of low refractive and high refractive materials, Thereby lowering the reflectance. However, in this method, since it is necessary to form multiple layers, the coating of SiO ₂ / TiO ₂ must be performed several times by the vapor deposition method, so that the process becomes complicated and the process cost increases.

On the other hand, the visibility of the display element is not determined only by the reflectance of the glass substrate. For example, when the surface of the glass substrate is contaminated, the external light is scattered by the contaminant and is diffused, thereby lowering visibility. Such contamination of the glass substrate can be prevented by treating the glass substrate.

Currently, a method of treating a glass substrate for preventing surface contamination has been proposed in which an inorganic material is coated to have a hydrophobic property on the surface and a method of making the surface hydrophilic. The surface treatment method having a hydrophobic property prevents water from being adsorbed on the surface of the substrate to prevent contamination by moisture and has a hydrophilic property to prevent oil from being adsorbed on the substrate surface to prevent contamination by oil.

As described above, the substrate processing method for preventing contamination complicates the process because different treatment methods must be performed for each type of contamination. In order to prevent both contamination by moisture and oil, the two steps must be repeated, Resulting in more complexity and increased manufacturing costs.

Furthermore, when both the low reflection coating and the anti-contamination coating are applied, there is a problem that the reflection of external light is rather increased due to the difference in refractive index between the anti-fouling coating film and the low reflection coating film.

An object of the present invention is to provide a method for surface treatment of a substrate, which can form a polymer layer in which fluorine-based polymer nanoparticles are dispersed, so that the surface of the substrate can be treated with low reflection and contamination resistance.

Another object of the present invention is to provide a display device or the like to which a surface-treated substrate is applied.

5A and 5B are a plan view and a cross-sectional view, respectively, showing an electrode structure of a touch panel to which the surface-treated transparent substrate of the present invention is applied.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the low reflection coating and the anti-fouling coating are performed by a single process, thereby reducing the reflectance of the transparent substrate or the glass surface and preventing the contaminants from sticking to the surface of the substrate. Accordingly, when the surface-treated substrate is applied to a display device, it is possible to prevent a decrease in visibility due to low reflection and diffused reflection of contaminants.

In the following description, such a substrate processing method is specifically described for a transparent substrate used for a display device or the like, but the present invention is not limited to a substrate applied to only such a specific product.

The present invention can be applied not only to a transparent substrate used for a display device such as glass or plastic but also to a surface treatment of a substrate of a touch panel or a 3D panel, and also to a surface treatment of a transparent lens of a camera.

In the present invention, the substrate is subjected to low reflection and contamination treatment using a fluorine-based polymer. The fluorine-based polymer has a low affinity for moisture and organic matters, and has excellent stain-resistance. Since the fluorine-based polymer has a low refractive index, when the layer is formed on transparent glass or plastic, the fluorine-based polymer can have a reflectance of less than 2% due to a difference in refractive index. Therefore, when the surface of glass or plastic is treated with a fluorine-based polymer as in the present invention, it is possible to prevent a decrease in visibility due to reflection or diffuse reflection of light.

In particular, in the present invention, the fluorine-based polymer is dissolved in a fluorine-based solvent to form fluorine-based nanoparticles, and the fluorine-based polymer is laminated on a transparent substrate to treat the surface of the substrate. The reason for the treatment is that it is not easily dissolved in a solvent and the affinity of glass or plastic is low. That is, fluorine-based polymers that are not well formed as thin films on glass and plastic are formed in the form of nanoparticles and laminated to low-reflect and contaminate the substrate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart showing an actual process of a transparent substrate according to the present invention; FIG.

As shown in FIG. 1, the fluorinated polymer is dissolved in 10 ml of a fluorinated solvent and stirred at room temperature for 1 hour or more to form a fluorinated polymer solution (S101). In this case, the fluorine-based polymer may include poly (hexafluoropropylene oxide), polytetrafluoroethylene-co-hexafluoropropylene, poly (decafluorooctyl acrylate ), Polytetrafluoro-3- (heptafluoropropoxy) propyl acrylate, polytetrafluoro-3- (heptafluoroethoxy) propyl acrylate (poly tetrafluoro-3- (heptafluoroethoxy) propyl acrylate, poly (tetrafluoroehtylene), tetrafluoroethylene hexafluoropropylene vinylidene fluoride, poly (undecafluorohexyl acrylate) ), Poly (nonafluoropentyl acrylate) , Polytetrafluoro-3- (trifluoromethoxy) propyl acrylate, poly (pentafluorovinyl propionate), polyheptafluoroacrylate (polytetrafluoroethoxy) propyl acrylate, poly (trifluoromethyl) acetate, poly (heptafluorobutyl acrylate), poly (trifluorovinyl acetate), poly 1,1,1,3,3,3-hexafluoroisopropylacrylate (poly 3,3-hexafluoroisopropyl acrylate, poly (octafluoropentyl acrylate), poly (methyl 3,3,3-trifluoropropyl siloxane), poly Poly (2,2,3,3,4,4,4-heptafluorobutyl methacrylate), polypentafluoropropyl acrylate (poly (2,2,3,3,4,4,4-heptafluorobutyl methacrylate) poly (pentafluoropropyl acrylate), poly 2,2,3,3,3-pentafluoropropyl acrylate (poly (2,2,3,3,3 poly (2-heptafluorobutoxy) ethyl acrylate, poly (chlorotrifluoroethylene), poly 1,1,1,3,3,3-pentafluoropropyl acrylate, Poly (1,1,1,3,3,3-hexafluoroisopropyl methacrylate) and the like can be used.

Examples of the fluorine-based solvent include 1,1,1-trichlorotrifluoroethane, 1,1,2,2-tetrafluoroethane, Hexafluoropropane, hexafluoroisopropanol, trifluoroethane, and trifluoroethane may be used as the solvent.

Subsequently, the fluorine-based surfactant is dissolved in 50 ml of a toluene solution (S102). In this case, the fluorine-based surfactant has a structure of C _n F _{2n +} - (Si (CH ₃ ) ₂ O) _m -SiH ₃ wherein n = 4 to 10 and m = 4 to 20.

Thereafter, the fluorine-based polymer solution is mixed with the toluene solution in which the surfactant is dissolved to form fluorine-based polymer nanoparticles (S103). At this time, the fluoropolymer solution and the toluene solution are mixed at a rate of 6 ml per minute (1: 5 ratio), and the mixed solution is stored at room temperature for 30 minutes to grow the polymer nanoparticles.

The polymer nanoparticles 1 formed in Fig. 2 are shown. 2, the polymer nanoparticle 1 comprises a spherical fluorinated polymer 2 and a fluorinated surfactant layer 4 formed in a peripheral region of the fluorinated polymer 2 to a predetermined thickness.

The polymer nanoparticles 1 thus prepared are formed in various sizes. In the present invention, only nanoparticles having a diameter of 50 to 400 nm are required. Therefore, the prepared polymer nanoparticles (1) The nanoparticles having a diameter of 400 nm or more are removed and only polymer nanoparticles having a diameter of 50 to 400 nm are left (S104).

As shown in FIG. 3, a solution in which polymer nanoparticles are dispersed is coated on a substrate 10 and dried to form a fluoropolymer layer 12 on the substrate 10 (S105). At this time, application of the polymer solution in which the polymer nanoparticles are dispersed may be performed by various methods such as spin coating, roll coating, dip coating, and screen coating. Spin coating is performed by placing a substrate on a rotating plate rotating at a constant speed and then dropping a solution in which the polymer nanoparticles are dispersed on the rotating substrate to spread the solution in which the polymer nanoparticles are dispersed to spread over the entire substrate. The roll coating is carried out by applying a solution in which the polymer nanoparticles are dispersed on the surface of the roller, then advancing the roller with the roller in contact with the substrate, and transferring the polymer nanoparticle dispersion solution on the surface of the roller onto the substrate .

In the dip coating, a solution in which the polymer nanoparticles are dispersed is filled in a container, and then the substrate is placed in a container and a solution in which the polymer nanoparticles are dispersed on the substrate is applied with wetting. The screen coating is performed by disposing a screen having an opening region on a substrate, supplying a solution in which the polymer nanoparticles are dispersed on the screen, applying pressure to a solution in which the polymer nanoparticles are dispersed by squeezing or the like, The solution in which the polymer nanoparticles are dispersed is discharged, so that the nanomaterial can be coated on the substrate. The method of applying the solution in which the polymer nanoparticles are dispersed is not limited to the above-mentioned specific method, but various methods can be used.

The fluoropolymer layer can be formed by removing the solvent by drying at 50 ° C for 1 hour in a decompression oven at 0.1 torr pressure in which the polymer nanoparticles thus coated are dispersed. At this time, the fluorine-based polymer layer 12 may be formed to a thickness of about 10-100 탆.

As shown in FIG. 3, polymer nanoparticles 1 of various sizes are dispersed in the polymer layer 12 formed on the substrate 10. Since the fluorine-based polymer layer 12 has low affinity with water or organic matter, organic substances such as moisture and oil are not adsorbed on the fluorine-based polymer layer 12, and contamination due to moisture or oil can be prevented. In addition, since the refractive index is low, the reflectance can be reduced to 2% or less when formed on a transparent substrate such as glass or plastic. Therefore, when applied to a display device or the like, deterioration of visibility due to reflection and scattering of external light can be prevented .

Such a substrate processing method of the present invention can be applied to various substrates. For example, it may be applied to a transparent substrate such as a display device, a transparent substrate of a functional panel such as a touch panel, or a glass lens of a camera.

Hereinafter, a display device to which a surface-treated substrate is applied will be described. In the following description, only the specific display element is described, but only one example is described, and the substrate on which the surface of the present invention is processed may be variously applied.

As shown in FIG. 4, the transparent first substrate 110 such as glass or plastic is surface-treated, and a first fluorinated polymer layer 105a made of fluorinated polymer nanoparticles is formed on one surface of the first substrate 110. Although the first fluorinated polymer layer 105a is formed on an outer surface of the first substrate 110, that is, a surface on which no other structures are formed, the first fluorinated polymer layer 105a may be formed on the surface of the first substrate 110 That is, on a surface on which other structures are formed.

A thin film transistor is formed on the surface-treated first substrate 110. The thin film transistor includes a gate electrode 111 formed on a first substrate 110, a gate insulating layer 122 formed over the entire first substrate 110 on which the gate electrode 111 is formed, A semiconductor layer 112 formed on the semiconductor layer 112 and a source electrode 114 and a drain electrode 115 formed on the semiconductor layer 112.

A protective layer 124 is formed on the entire surface of the first substrate 110 on the thin film transistor. A strip-shaped common electrode 126 and a pixel electrode 127 having a constant width are arranged parallel to each other on the protective layer 124 so that the surface and the transverse electric field of the first substrate 210 are perpendicular to the common electrode 126 and the pixel Electrodes 127 are formed. The pixel electrode 127 is electrically connected to the drain electrode 115 of the thin film transistor through the contact hole 125 formed in the passivation layer 124 so that an image signal is transmitted from the outside through the thin film transistor to the pixel electrode 127 . The common electrode 126 and the pixel electrode 127 are made of a metal or a transparent metal oxide such as ITO (Indium Tin Oxide).

A transparent second substrate 130 such as glass or plastic is surface-treated, and a second fluorinated polymer layer 105b made of fluorine-based polymer nanoparticles is formed on one surface. Although the second fluorinated polymer layer 105b is formed only on the outer surface of the second substrate 130, the second fluorinated polymer layer 105b may be formed on the inner surface of the second substrate 130, As shown in FIG.

A black matrix 134 and a color filter layer 136 are formed on the second substrate 130. The black matrix 234 is made of Cr or CrOx and prevents light from being transmitted to the image non-display region, such as the gate line, the data line formation region, and the thin film transistor formation region of the display element, . The color filter layer 136 is formed of R, G, and B color filter layers to realize an actual image.

Although not shown in the drawing, an overcoat layer may be formed on the color filter layer 136 to protect the color filter layer 136 and flatten the surface.

As described above, in the liquid crystal display element according to the present invention, the surface of the substrate is treated to form a polymer layer in which the fluorine-based nanoparticles are dispersed, thereby reducing the reflectance and preventing contamination by moisture or oil, It is possible to prevent deterioration of visibility due to diffuse reflection.

On the other hand, in the above description, both the first substrate and the second substrate are surface-treated, but only the second substrate may be surface-treated. Since the user recognizes the image to be emitted through the outer surface of the second substrate 130 when the user realizes the image by using the actual liquid crystal display element, Reflected or scattered to deteriorate the visibility of the user. Therefore, in the case of the display element, a desired effect can be obtained even if only the surface of the substrate, which is the main cause of external light reflection, is processed.

The first electrode 217 is formed to the upper portion of the first bridge electrode 213 in the removed region of the insulating layer 215, (217) is electrically connected to the first bridge electrode (213). Since the first bridge electrode 213 is exposed at the both ends of the first bridge electrode 213 and the first bridge electrode 213 is electrically contacted with the exposed region, The first electrodes 217 are electrically connected to each other and a plurality of first electrodes 217 arranged along the X axis direction are electrically connected as a whole.
