[Prior Art] A liquid crystal display uses an optical anisotropy and a multi-refracting property of a liquid crystal molecule to display an image; when an electric field is applied, the arrangement of the liquid crystal changes, and the light transmission characteristics change depending on the arrangement of the liquid crystal. Generally, a liquid crystal display is provided with two substrates on which electric field generating electrodes are respectively formed, and opposite surfaces are formed to form two electrodes. After a liquid crystal substance is injected between the two substrates, a voltage is applied to the two electrodes to form an electric field; The electric field liquid crystal molecules move to change the transmittance of light to display an image. The structure of a widely used thin film transistor liquid crystal display (TFT_LCD) is as follows: a lower substrate (also referred to as an array substrate) on which a thin film transistor and a pixel electrode are arranged; an upper substrate (also referred to as an upper substrate) For the color line light film ((7)(10)丨(4) substrate, the structure of the upper substrate is 'the black matrix and the red, green and blue colored layers are repeatedly disposed on the upper portion of the substrate formed of plastic or glass, for protection thereon The color filter sheet and the surface smoothness are formed to form an outer protective layer ((10)(10)) having a thickness of i to 3 μm made of a material such as polyimide, polyacrylic acid vinegar, polyglycolic acid, and the like. An IT〇 (lndium Tin 〇 〇 锡 tin oxide) transparent conductive layer for driving a liquid crystal and a liquid crystal is formed on the layer, and a liquid crystal is filled between the upper substrate and the lower substrate; the two sides are respectively attached to the visible light The line (natural light) is optically polarized, and the polarizer is applied to the TFT through the external peripheral circuit, and the voltage is applied to the TFT (the tunw) state. Apply zero-sequence voltage (after the state of the surface: 'wire' voltage in the liquid crystal (four) miscellaneous information, electrical closure (1 trace 0ff), save the electricity stored in the liquid crystal charger and auxiliary charger, so that the shirt is not visible - The time is set. When the liquid crystal is applied with electricity, the arrangement of the liquid crystal changes, and the liquid crystal passes through the liquid crystal at 201214046. This light is transmitted through the polarizing plate to obtain the desired image. The color filter is usually in plastic. Or a black matrix formed on a transparent substrate made of glass, and different colors such as red, green, and blue are sequentially formed by photolithography, printing, inkjet, etc. a color pattern such as a mosaic or a mosaic. The black matrix in the color filter substrate blocks uncontrolled light penetrating outside the transparent pixel electrode of the substrate to improve contrast; the red, green, and blue color layers can be white. Light: a light having a specific wavelength penetrates and develops color; a transparent conductive film can function as a common electrode that applies an electric field to the liquid crystal. However, the upper color filter substrate and the lower array are used. When the column substrate is combined to produce a liquid B panel, the leakage probability is extremely high due to the combination error of the color filter substrate and the array substrate. Therefore, in order to prevent such light leakage, a certain margin is left when designing the black matrix. (margin) to design, and this edge will become the main reason for eroding the aperture ratio. In order to improve this problem, it has recently been attempted to form a color filter of a liquid crystal display to form a substrate (ie, an array substrate) instead of an upper portion. The substrate (i.e., the color slab substrate) is used to increase the aperture ratio, and the manufacturing steps are reduced to reduce the manufacturing cost. SUMMARY OF THE INVENTION An object of the present invention is to provide a photopolymerizable resin composition which is formed when a cured film is formed. Appropriate optical density simultaneously reduces the content of specific metals, thereby reducing the poor driving performance of the liquid crystal display and the deterioration of image quality or optical performance. Another object of the present invention is to provide a photopolymerizable resin composition having a color filter formed on an array substrate in the structure in which a color filter is formed on the array substrate when the liquid crystal display is manufactured. Matrix and spacer for liquid crystal cell gap maintenance. Still another object of the present invention is to provide a photopolymerizable resin composition which is useful for forming a pattern which can simultaneously satisfy the black matrix function on the array substrate and the liquid crystal cell gap maintenance work. A further object of the present invention is to provide a photopolymerizable resin composition which does not hinder the maintenance of the applied voltage even if a color filter is formed on the array substrate. 201214046

When the optical density (OD) of the thickness is less than 3.0, it is difficult to exhibit an appropriate light-shielding effect when it is increased to a certain thickness. When the light-shielding film is used, the light-shielding effect is not sufficiently exhibited, and the transmission to the region other than the transparent pixel cannot be blocked. Light. If a photopolymerizable resin composition satisfying the above characteristics is used, it can be patterned using a slit mask or a half-tone mask to have a height difference of a predetermined width. The black matrix and the gap maintaining spacers; or the gap maintaining spacers are further formed at the positions where the black matrix is formed, and the gap maintaining spacers can function as the black matrix. In particular, after the pattern is formed, when a transparent electrode is formed in the subsequent photolithography step, the pattern caused by the stripping liquid can be minimized. In addition, as described above, the image of the liquid crystal display is displayed in this manner. The liquid crystal substance is injected between the two substrates facing the two electrodes (pixel electrode, common electrode), and a voltage is applied to both electrodes to transmit the liquid crystal molecules through the electric field. To change the light transmittance "if a conductive foreign matter (metal 201214046 oxide) is mixed between the pixel electrode formed on the lower substrate and the common electrode formed on the upper substrate", the pixel electrode formed on the lower substrate and the common electrode formed on the upper substrate The potential difference between the electrodes cannot be maintained in the initial state of application, and the liquid crystal molecules are not subjected to alignment or misalignment. These problems can cause spots such as bright spots or black spots when the liquid crystal display is driven, and pixel defects occur. In order to minimize the metal content of the black matrix hardening pattern prepared by using the photopolymerizable resin composition, there are various specific methods and are not particularly limited. Specifically, it may be a method of changing the type and content of the black pigment. Hereinafter, examples and comparative examples of the present invention will be described in detail. However, the examples and comparative examples are only intended to better illustrate the invention and not to limit the scope of the invention. <Preparation Example ι> Preparation of Compound represented by Chemical Formula 1 In a 1 L four-necked flask, 232 g of a bisphenol type epoxy compound, 72 g of acrylic acid, and 4.56 g of diethylamine and a solvent of hydroquinone were added to the solvent.

In contrast, the aniline black of Example 1-4 was used. When the resin composition of the pigment and the manganese oxide black pigment forms a cured film, it can display appropriate light and density, and the specific metal content can be minimized, so that spots such as bright spots or black spots occur when the liquid crystal display is driven (Sp 〇t) The problem of poor pixels.
