  Recently, as a light source of a liquid crystal display (LCD), instead of a conventional CCFL, an LED or an OLED element that emits light without being driven or liquid crystal is often used. In general, when an LED or OLED is used as a light source, red, green, and blue light is emitted by itself, so that no separate color filter is required.

  However, in general, a color filter is used to improve the color purity of light emitted from an LED or OLED light source to achieve a high color reproduction rate. In particular, when white light is produced using an OLED light source, a color filter is always necessary for color classification.

  Only when the spectrum emitted from the light source and the absorption and transmission spectra of the color filter are appropriately combined, the color purity can be increased and the color reproduction and luminance can be improved.

  The color filter can be manufactured using a photosensitive resin composition containing a styryl compound represented by Chemical Formula 1. A color filter can be formed by applying the photosensitive composition onto a substrate to form a coating film, and exposing, developing and curing the coating film.

  The photosensitive resin composition according to an embodiment of the present specification is excellent in heat resistance, has little color change due to heat treatment, has a high color reproduction rate even during the curing process during the production of a color filter, and has brightness and contrast. A high color filter can be provided.

  The substrate may be a glass plate, a silicon wafer, and a plate of a plastic substrate such as polyethersulfone (PES) or polycarbonate (Polycarbonate, PC), and the type thereof is not particularly limited. .

  The color filter may include a red pattern, a green pattern, a blue pattern, and a black matrix.

  In another embodiment, the color filter may further include an overcoat layer.

  A grid-like black pattern called a black matrix can be arranged between the color pixels of the color filter for the purpose of improving contrast. Chrome can be used as the black matrix material. In this case, it is possible to use a method in which chromium is deposited on the entire glass substrate and a pattern is formed by an etching process. However, a resin black matrix by a pigment dispersion method capable of fine processing can be used in consideration of high process cost, high reflectivity of chromium, and environmental contamination due to chromium waste liquid.

  In the black matrix according to an embodiment of the present specification, a black pigment or a black dye can be used as a coloring material. For example, carbon black can be used alone or a mixture of carbon black and a coloring pigment can be used. At this time, since a coloring pigment that lacks light-shielding properties is mixed, the amount of the coloring material is relatively small. Even if it increases, there exists an advantage which the intensity | strength of a film | membrane or the adhesiveness with respect to a board | substrate does not fall.

  A display device including a color filter according to the present specification is provided.

  The display device includes a plasma display panel (PDP), a light emitting diode (LED), an organic light emitting diode (OLED), a liquid crystal display (LCD), and a liquid crystal display (LCD). It may be any one of a liquid crystal display device (Thin FIlm Transistor-Liquid Crystal Display, LCD-TFT) and a cathode ray tube (CRT).

  The display device according to an embodiment of the present specification has a high color reproduction rate, a high luminance and a high contrast, and an excellent high light shielding property. With such characteristics, the display device can be manufactured slim.

  Further, in one embodiment of the present specification, the display module itself can be made slim and the display can be maximized by using the bonded portions of the upper and lower plates of the module with a minimum area.

  Hereinafter, the present specification will be described in detail with reference to examples. The following examples are intended to illustrate the present specification, and the scope of the present description includes the ranges described in the following claims and their substitutions and modifications, and is limited to the scope of the examples. Not.
