Description

A7 468063 __B7______ V. Description of the invention (1) [Technical Field of the Invention] • The present invention relates to a filter used for the manufacture of color image tube components and color liquids (please read the precautions on the back before filling this page) A radiation-sensitive composition for a blue filter of a color filter, and a color filter having pixels formed using the radiation-sensitive composition. [Prior technology] Generally, color filters for color image tube elements, color liquid crystal display devices, etc. are mostly irradiated with a photosensitive resin coating film through a photomask (hereinafter referred to as "exposure") to harden the exposed part. After the undeveloped part of the coating film is removed by post-development treatment to form a pixel pattern, a method of dyeing (staining method) or a composition capable of dispersing or dissolving the coloring agent of the photosensitive resin is used, as described above. It is prepared by etching printing methods such as coating film, exposure and development. In addition to the three primary colors of red, green, and blue, these color filters can be used in combination with complementary colors such as cyan, magenta, and yellow, especially in color image tubes. In addition, in a color liquid crystal display device, when a liquid crystal is driven, a transparent electrode made of indium oxide or tin oxide is usually formed on a color filter by evaporation or electroplating, and the liquid crystal is formed in a specific direction on the color filter. Orientation film is also formed during orientation. Therefore, in order to obtain transparent electrodes and orientation films with barrel properties, the temperature during manufacture generally needs to be above 200 ° C, preferably at a high temperature above 250 ° C. Among the color filters prepared according to the method described above, 'color filters using dyes have extremely high transparency to radioactivity, so their resistance to cooking is not sufficient, .....--. .......— i. Therefore, if the temperature for making the transparent electrode and orientation film is lower than 200 ° C, the paper size is applicable _ National Standard (CNS) A4 specification (210 X 297 public love) A7 468063 B7__ V. Description of the invention (2) (Please read the precautions on the back before filling in this page). If you do this, problems such as failure to ensure the performance of transparent electrodes or alignment films will occur. In addition, a color filter using a dye has poor light resistance, and therefore has a disadvantage that it is not suitable for outdoor use. Therefore, in recent years, from the viewpoints of heat resistance and light resistance, pigments, in general, organic dyes are often used in place of dyes. However, in recent years, with the improvement of the quality and use of accompanying color video tube devices and liquid crystal display devices, there has been a great demand for display panels with high brightness. The brightness of the display panel is evaluated based on the white balance stimulus (Y), but this stimulus (Y) has a correlation with the color reproduction range as an indicator of the displayable tonal range. That is, in general, when the color reproduction range is to be enlarged, the color density needs to be increased, but at the same time, the stimulus (Y) of white balance is reduced. The color reproduction range of the display panel is generally based on the area of the color triangles of the three primary colors as determined by NTSC (National Television System Committee; United States). "" Means that the larger the color reproduction range, the larger the meaning. Therefore, when achieving the high brightness of the display panel, it is a research goal of how to maximize the white balance stimulation (Y) without reducing the NTSC ratio, such as making a color filter with an NTSC ratio of 44%. "Their" white balance "stimulus (Y) is preferably 37 or more. Therefore, for each radiation-sensitive composition of blue, red, or color filter, there are various stimuli that study how to improve its white balance. Research on (Y), but even if the radiation-sensitive components that can be red or green can be enhanced, the paper size of the CIE form applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 468063 A7 ____B7_ V. Invention Note (3) (Please read the precautions on the back before filling out this page), but when the blue radiation-sensitive composition, the stimulus 値 (Y) in the CIE color system will be extremely It is not easy to increase with the increase of the white balance stimulus (γ). Therefore, when the NTSC ratio of the color filter used for display panels was 44%, the white balance stimulus 値 (Y) was only high. 3 5 or so ... Therefore, the blue The pixel-sensitive radiation composition requires a material that can bring high brightness to the display panel and have sufficient color reproduction range. [Objective of the Invention] The present invention is to provide a display panel that can be brought to the display panel in view of the above problems. A radiation-sensitive composition for a blue color filter with high brightness and a sufficient color reproduction range is an object of the invention.
