Description

  The present invention relates to a self-luminous photosensitive resin composition, a color filter produced using the same, and an image display device.

  Recently, the display industry has rapidly changed from a CRT (Cathode-Ray Tube) to a flat panel display represented by PDP (Plasma Display Panel), OLED (Organic Light-Emitting Diode), LCD (Liquid-Crystal Display) and the like. . Among them, the LCD is widely used as an image display device used in almost all industries, and its application range is continuously expanding.

  The LCD adjusts the transmittance while white light generated from the backlight unit passes through the liquid crystal cell, and mixes the three primary colors that are transmitted through the red, green, and blue color filters. And full color is realized.

  As a light source of the backlight unit, CCFL (Cold Cathode Fluorescent Lamp) is used. However, in this case, since the backlight unit must always apply power to the CCFL, there is a problem that power consumption is consumed. In addition, the color reproducibility of about 70% compared to the existing CRT and environmental pollution problems associated with the addition of mercury have been pointed out as disadvantages.

  As an alternative to solve the above problems, research on a backlight unit using an LED (Light Emitting Diode) is being actively conducted.

  When the LED is used in a backlight unit, it can provide a more vivid image quality to the consumer, exceeding 100% of the NTSC (National Television System Committee) color reproduction range specification.

  Therefore, in the same industry, in order to improve the efficiency of the backlight light source, a method through a change in the material and structure of the color filter and the LCD panel has been proposed.

  The color filter forms a pixel of each color through a patterning process after applying a dispersion composition including a pigment or a dye. However, the pigment and the dye cause a problem of reducing the transmission efficiency of the backlight light source. The reduction in the transmission efficiency results in a reduction in color reproducibility of the display device, and it is difficult to realize a high quality screen after all.

  The problem of low color reproducibility can be eliminated through increasing the light efficiency of the color filter, thereby increasing the thickness of the color filter, or the color conversion layer (or light conversion layer) laminated or close to the color filter. A method of introducing is proposed.

  In connection with this, Korean Patent Publication No. 2010-0056437 uses a inkjet method to absorb light of a specific wavelength on a color filter layer and output light including a wavelength different from the absorbed wavelength. A method for forming a conversion layer is disclosed, and Korean Patent Publication No. 2012-0048218 discloses a color filter including a light changing portion containing a fluorescent material.

  However, such a method has a problem that the process for the formation of the color filter layer and the color conversion layer has to be produced, which complicates the process and increases the process time.

Korean Patent Publication No. 2010-0056437 Korean Patent Publication No. 2012-0048218

There is an advantage that it is possible to manufacture a color filter and an image display device that can also perform the above-mentioned role.

  In addition, when a color filter and an image display device are manufactured using the self-luminous photosensitive resin composition according to the present invention, the process is performed by forming a single color conversion layer that does not include a separate color filter layer. The process time can be simplified and the color filter layer alone can substitute for the role of the color filter layer, and the fluorescent efficiency is excellent.

FIG. 1 is a diagram schematically illustrating a color filter including a conventional color filter layer and a color conversion layer. FIG. 2 is a diagram schematically showing a color filter including only the color conversion layer of the present invention.

<Color filter>
Another aspect of the present invention relates to a color filter including a color conversion layer manufactured using the above-described self-luminous photosensitive resin composition.

  The color filter according to the present invention includes a color conversion layer manufactured with the self-luminous photosensitive resin composition of the present invention including a fluorescent dye and a pigment, so that excellent fluorescence efficiency can be obtained without including a separate color filter layer. Even if only a single layer configuration of the color conversion layer is used, there is an advantage that the roles of the existing color filter layer and the color conversion layer are substituted.

  Further, in comparison with the conventional color filter manufacturing process in which the color conversion layer 20 and the color filter layer 30 are laminated on the substrate 10, the color filter of the present invention is obtained by laminating the color conversion layer 20 directly on the substrate 10. Since the separate color filter layer 30 is not formed, the manufacturing process for forming the color filter layer 30 is excluded, so that the manufacturing process of the color filter can be simplified, thereby reducing the process time. (See FIGS. 1 and 2).

  The color filter includes a substrate and a pattern layer formed on the substrate.

  The substrate may be the substrate for the color filter itself, or may be a part where the color filter is located on a display device or the like, and is not particularly limited. The substrate may be glass, silicon (Si), silicon oxide (SiOx), or a polymer substrate, and the polymer substrate may be made of polyethersulfone (PES) or polycarbonate (PC). There may be.

  The pattern layer is a layer containing the self-luminous photosensitive resin composition of the present invention, and is a layer formed by applying the self-luminous photosensitive resin composition, exposing, developing and thermosetting in a predetermined pattern. There may be. The pattern layer may be formed by performing a method generally known in the art.

  The color filter including the substrate and the pattern layer as described above may further include a partition formed between the patterns and may further include a black matrix, but is not limited thereto.

  In addition, the color filter may further include a protective film formed on the pattern layer.

  The color filter may include one or more selected from the group consisting of a red pattern layer, a green pattern layer, and a blue pattern layer. The red pattern layer, the green pattern layer, and the blue pattern layer can emit red light, green light, and blue light when irradiated with light, respectively. At this time, the emitted light of the light source is not particularly limited, but more excellent. From the viewpoint of color reproducibility, a light source that emits blue light can be used.

<Image display device>
Still another embodiment of the present invention relates to an image display apparatus including the color filter described above.

  The color filter of the present invention is applicable not only to a normal liquid crystal display device but also to various image display devices such as a total light emitting display device, a plasma display device, and a field emission display device.

  The image display device includes a color filter containing a cured product of the self-luminous photosensitive resin composition containing the fluorescent dye and pigment of the present invention, and exhibits excellent fluorescence efficiency without a separate color filter layer. There is an advantage that the role of the existing color filter layer and the color conversion layer can be substituted by the color conversion layer alone without the color filter layer. In addition, since the process of forming a separate color conversion layer is excluded in the manufacturing process of the image display device, the manufacturing process of the image display device can be simplified, thereby reducing the process time. There is.

  According to an embodiment of the present invention, the image display apparatus may further include a light source, and specifically, the light source may emit blue light. In the case of an image display device that does not require a light source (for example, OLED), there is no relationship, but when a light source is included as described above, the wavelength of light emitted from the light source (for example, 400 to 480 nm for blue light) And the wavelengths emitted from the fluorescent dyes contained in the color conversion layer appear to be mixed with each other, thereby causing a problem that the fluorescent efficiency of the fluorescent dyes is lowered. However, the self-luminous photosensitive resin composition according to an embodiment of the present invention includes a pigment together with a fluorescent dye, thereby absorbing the wavelength of light emitted from the light source by the pigment and improving the fluorescent efficiency of the fluorescent dye. There are advantages. As an example, when blue light is used as the light source, it includes a pigment having a maximum absorption wavelength range of 380 to 550 presented as an embodiment of the present invention, thereby absorbing the wavelength emitted from the light source. Thus, there is an advantage that only the wavelength emitted by the fluorescent dye is shown, that is, the fluorescent efficiency of the fluorescent dye can be prevented from being lowered. In addition, when a light source other than blue light is used, various fluorescent dye and pigment combinations can be used in consideration of the wavelength condition of light emitted from the light source.
