The features and implementations of the present invention are described in detail with reference to the preferred embodiments. [Embodiment] The embodiments described in the drawings are now referred to, and the same reference numerals are used in the drawings to refer to the same parts. A liquid crystal display device using ultraviolet curable liquid prepolymer, using the ultraviolet curable liquid prepolymer as a sizing material, and a method of manufacturing the same will now be described with reference to the drawings. Ultraviolet curing of liquid prepolymers allows for the minimization of shrinkage of certain materials during heat treatment by altering or substituting certain ingredients. The curing and thermal properties of the functional groups in the liquid-cold prepolymer based on UV-curing 200827931 will now be described. The functional group is broad at one end of the chemical reaction between the monomer compound and the polymer. For example, a single functional group has one end of a chemical reaction of a monomeric compound with a polymer. That is, the dual function group or the trifunctional group has two or three ends in which the monomer compound chemically reacts with the polymer. ''Fig. 4A'' to '4C' show the volume change of the UV-curable liquid pre-polymer containing the single-energy group during the curing process and heat treatment. For example, the ultraviolet curable liquid pre-polymer 51 is formed on a substrate (not shown), wherein the ultraviolet-curable liquid prepolymer 51 includes monomers (M) each having a single function group, and each having a single function group The working end serves as a photoinitiator (I) which induces the initiator of the initial reaction on the monomer (M). The external solidified liquid state compound is activated by ultraviolet light (four), and each monomer including a single functional group has an active end. As shown in "Fig. 4B", after the pattern layer 52 is cured by ultraviolet irradiation, the thin and plate-form of the ultraviolet-curable liquid prepolymer is formed into a linear chain structure. Since the monomer (M) having a single functional group is activated from the initiator (I)*, each of the activated ends is combined with another monomer, and the combination, enthalpy; Jc plane is formed to form a linear chain structure. After the curing process, the linear chain structure is stacked or stacked at regular intervals, wherein each linear chain structure is a horizontal arrangement of the water linear chain structure after the curing process, and the film of the ultraviolet curing liquid pre-extracting material is solidified to form _ layer 52. For example, "Development of the pattern layer formed by the additional heat treatment by the right side of the 4C picture|中中斤+,*-7..." causes a sharp increase in the linear chain structure between the pieces, resulting in the occurrence of the whole body of the 2008 layer. When the complex linear chain structure is configured horizontally, there is a fixed distance between the linear chain structures after the curing process. Due to the implementation of the additional heat treatment, the reduction in the distance between the linear chain structures causes the shrinkage of the pattern layer 52a. Therefore, including the single function group The monomeric ultraviolet curing prepolymer is cured, wherein the pattern layer 52a is shrunk such that the volume of the cured pattern layer is small relative to the initial coating pattern layer shown in "Fig. 3". Usually, the linear chain structures formed during the curing process are stacked in a plurality of layers such that the thickness of the pattern layer is largely shrunk. To overcome the severe shrinkage of the UV-cured liquid prepolymer after additional curing by the heat treatment process, UV-cured liquid prepolymers are based on the assumption that the UV-curable liquid prepolymer comprising a single functional group shrinks during curing due to structural properties. It is necessary to include a polymer having a dual function group or a triple function group. If the UV-curable liquid prepolymer comprises a polymer of a dual function group or a trifunctional group, the volume of the UV-curable liquid prepolymer remains fixed even when cured or heat treated. The 5A map to the 5C map contains volume changes of the UV-curable liquid prepolymer that does not include the branch or crosslinked functional group after the curing process and heat treatment. As shown in "Fig. 5A", the ultraviolet curable liquid prepolymer comprises a single functional monomer (M) of about 3 〇 to 60 ° / ◦ volume, and a double functional monomer of about 2 〇 to 5 〇 % by volume. ), about 10 to 20% by volume of the three functional monomer (τ) and the light pickup (1). The single functional monomer (Μ) is composed of CH2=CHY or CH2=CXY, wherein "X" and "γ" are composed of any of halogen, alkyl, ester or phenyl. The single functional monomer (M) usually consists of a vinyl monomer having a carbon covalent bond structure. 11 200827931

As a result, the volume of the pattern layer 21G is fixed. In particular, for the structure of the pattern layer 210 in which the linear chains are sequentially stacked, the change in the thickness of the cross-links and the branches can be minimized. ° For the following reasons, the UV-curable liquid prepolymer comprises about 30 to 60% by volume of the single functional monomer CM), about 20 to 50% by volume of the dual functional monomer (D) and about 2 to 2 〇 °. Volumetric three-function monomer (τ). As the number of functional groups increases, the number of connections and branches also increases through the activation of functional groups. The shrinkage of the UV-curable liquid prepolymer is minimized by an external heat treatment after the curing process. However, the viscosity is also increased with the number of functional groups. Therefore, when a pattern is formed by providing a scale mold selection, for example, a soft mold applied to a substrate coated with an ultraviolet curing liquid prepolymer, the mobility and the reaction speed are lowered, and it is difficult to obtain a desired pattern on the substrate. Therefore, the viscosity increase of the UV-curable liquid prepolymer is limited to a maximum of 14 200827931. The UV-curable liquid prepolymer is provided in an amount of about 20% by volume or more of the trifunctional monomer to form the desired pattern. In order to limit the increase in viscosity, the UV-curable liquid prepolymer may include a dual function monomer and a trifunctional monomer to ensure thermal stability. The dual functional monomer and the trifunctional monomer assist in branching and cross-linking via activation of ultraviolet light. The use of dual-function monomers, three-function monomers, and single-function monomers provides greater thermal stability than using only single-function monomers. (When only dual-functional monomers and tri-functional monomers are used, the reaction rate for activating each monomer using ultraviolet irradiation is reduced due to a large number of functional groups. In this respect, UV-curable liquid prepolymers necessarily require a single function. The monomer can improve the reaction rate and obtain appropriate viscosity by providing about 3% to about '6% by volume of a single functional monomer. The ultraviolet curing liquid prepolymer is used for pattern formation according to the following steps. First, prepare a mold structure such that the back surface of the mold structure has a back surface, and the back surface has a concave surface and a convex portion. (J; the substrate is coated with the ultraviolet curing liquid prepolymer relative to the mold structure. Then, the mold structure is Introducing the contact ultraviolet curing liquid prepolymer, followed by curing 'so that a predetermined pattern corresponding to the concave and convex portions of the mold structure is formed on the surface of the external and external solidified liquid prepolymer. Thereafter, the mold structure is combined with the ultraviolet curing liquid prepolymer The predetermined pattern is separated. As explained above, 'ultraviolet-cured liquid prepolymer can be applied to non- The process of the exposure process and the structure of the prayer pattern. For example, after the liquid prepolymer coating base 15 200827931 is cured by ultraviolet light, the 'predetermined pattern can be formed in the ultraviolet curable liquid prepolymer via printing. As shown in Fig. 5A When the UV-curable liquid prepolymer is used for a liquid crystal age device having a white additional structure, the self-color filter layer and the protective film layer can be simultaneously formed via ultraviolet, liquidated prepolymer. The material and the self-color filter layer and the film layer can be formed by ultraviolet curing of the (four) prepolymer. r , . "Brush chart 6" shows a cross-sectional view depicting a liquid crystal display device using ultraviolet curing liquid prepolymer As shown in "Fig. 6," the liquid crystal display device includes an ultraviolet curing liquid prepolymer which is a pattern layer.

And 'the first substrate 1 〇 A masking layer m is formed, which is formed in other portions of t other than the sub-pixels. The red, green, and blue color filter layers 112 are respectively disposed in the red, green, and blue sub-pixels, and the planarization pattern layer 210 is formed. The entire surface of the mask layer ln and the red, green and color filter layers 112 is formed. The planarization pattern layer 21 is formed of the above-mentioned ultraviolet-curable liquid prepolymer. The planarization pattern layer 210 is applied via an application. 3〇~6〇% of the single functional monomer (M), about 20~50〇/〇 volume of the dual functional monomer (D) and about 1〇~2〇% of the volume of the three functional monomer (T) Formed by the coating of the external solidified liquid prepolymer. 16 200827931 If the planarization pattern layer 2K) is formed by the above red, green, blue and white sub-pixels, the planarization map layer 210 is white as a white sub-pixel. The filter layer η; also serves as the protective film layer 114 in other regions. As shown in the figure, the planarization pattern layer 210 has a convex portion above the light shielding layer 111, so that the planarization pattern layer 21 can be used as the cylindrical spacer 115. - The inter-column fins 115 and the planarization pattern layer 21 can be formed in different steps. In this case, the planarization layer is formed entirely outside the region of the cylindrical spacer of the substrate (the surface is flatly formed. As shown in the figure, the plural layers are formed together by the planarization pattern layer, so that it can be reduced The number of steps of the first substrate 100. - preparing a second substrate having a thin film transistor array with respect to the first substrate having the color filter array. The thin film transistor array includes a gate and a data line at each sub-pixel The adjacent gates and the staggered interleaved _ transistors and the boundaries of the pixel electrodes in each sub-pixel are interlaced with each other. The pixel electrodes can alternate with the pixel electrodes in each sub-pixel. Then the first calibration layer 118 is formed. On the entire surface of the first substrate 1A including the planarization pattern layer 210, and the second alignment layer (not shown) may be axially included on the second blank surface of the crystal cut. In FIG. The patterned layer 21 has a flat upper surface corresponding to the red, green, blue, and white sub-pixels after the alignment layer is formed. By forming the planarization pattern layer 210, a white filter layer ι 3 that is reduced by the white sub-pixel can be provided. And The film layer 114 is configured to planarize the first substrate 1 including the light shielding layer m. After curing the planarization pattern * layer 210, the 'planar pattern layer is added to the intermediate junction and the sealing is improved. 17 200827931 = and 'planarization The pattern layer 21G maintains its volume without being substantially contracted by its high thermal stability so that an additional heat treatment is performed after the planarization pattern layer 21 is formed to form a calibration. The portion corresponding to the white sub-pixel does not be recessed or shrunk, so that The planarization pattern layer 210 maintains a uniform thickness. Next, a liquid crystal layer is formed between the first substrate 1 including the color filter array and the second substrate (not shown) of the secret film transistor array. The sealant of the Wei population is formed on the first or second substrate, and the liquid crystal material is applied to the substrate having the sealant. The first and second substrates are then bonded to each other. In another method, the inlet is applied. Formed on the first or second substrate, and the first and second substrates are bonded to each other. By using a capillary phenomenon and a pressure difference, the liquid crystal material is injected into the space between the first substrate and the second substrate via the inlet. The external solidified liquid prepolymer and the liquid crystal display device using the ultraviolet curable liquid prepolymer have the following advantages. First, the predetermined pattern portion can be prevented from shrinking due to heat treatment. Second, the ultraviolet curable liquid prepolymer can be used for one. Forming a white filter layer, a protective film layer and a cylindrical spacer, wherein the ultraviolet curing liquid prepolymer comprises a predetermined ratio of a dual function monomer, a trifunctional monomer, and a single function, a monomer. Therefore, even if the ultraviolet curing liquid is used The heat treatment after the prepolymer is patterned can also avoid the shrinkage or reduction of the volume of the ultraviolet curing liquid prepolymer having a branched or crosslinked structure, thereby reflecting the heat-resistant ultraviolet curing liquid prepolymer. The use avoids shrinkage or depression of the white sub-pixel portion, thereby providing a high quality image device and avoiding tissue gaps. 18 200827931 The invention is described in the foregoing, and is not intended to limit the invention.
