Description

201137519 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a white photosensitive resin composition. In particular, there is provided a photosensitive resin composition for preparing a white light-shielding layer, a white matrix obtained by applying the photosensitive resin composition, a color filter including the white matrix, and containing A reflective display element of the color grading sheet. [Prior Art] In the development of flat panel displays (FPDs), liquid crystal displays are most widely used in various applications due to their thinness and miniaturization. However, a transmissive liquid crystal display having a backlight generally causes fatigue when the eyes are exposed for a long period of time, and the optical characteristics of the liquid crystal display are liable to vary with the change of the viewing angle. In order to improve the above problems, there has been development of a reflective display which is thinner than a liquid crystal display, more power-saving, and less burdensome on the eyes. A reflective display is a display that displays an image by taking an external ambient light source and reflecting it, and such a display is specifically a reflective liquid crystal display, an electronic paper (electraiic paper) # related reflective display. "Electronic paper is a surface-display technology that converts paper on paper. The above-mentioned "paper" is actually made of organic electronic materials, which use microspheres that can be affected by electric fields to display images. The microspheres contain a conductive plastic. The way of pixel transformation is to use a transformation method similar to a personal computer display to further update the page by transforming the pixels. The development of electronic paper is the most popular in the _ _ era by the Japanese business (4) (Xer〇x) 201137519 developed Gyrieon Bead pigment, twisting the ball is black on one side and white on the other side with electrostatic microspheres, The sphere will rotate due to the change of the electric field, and the black and white button will be achieved, which will produce a picture of the file. In the 1990s, another type of electronic paper pigment was invented by the Massachusetts Institute of Technology J〇seph Jac〇bs〇n, which featured microcapsules (micr0capsules) instead of traditional pellets, and filled with color in capsules. The oil and the charged white particles, through the control of the external electric field, cause the white particles to go up or down the axis. When the white chicks are up (close to the direction of the clearer), white is displayed, when the white is down (When the direction of the person is in the direction of the person), the oil is displayed in color. This type of electronic paper is essentially a re-use of electrophoresis technology, and the use of the sputum sac makes it a soft plastic substrate instead of glass. Due to the development of color electronic paper display devices. In principle, there are two different ways to get a color image. First, you can use the color = GB / _ particles instead of white particles, or you can put the color filter δ on the top of the electronic paper display to achieve a color display. The hard electronic paper display can be used to make color enamel on the glass substrate. This method requires the color filter on the glass and electronic paper display components to be aligned and assembled. . If it is a tilted electronic paper ride H, it is completely impossible to use the square wire described above as a color calender. e The cost of her * is directly formed on the electronic paper display layer (4) I, 'Figures. The color glazing sheet is formed of a photosensitive resin composition. The public license 2_-531727 is to directly form the 201137519 light film on the electronic paper layer. The color light-receiving sheet is formed of a photosensitive resin composition, /, and a pattern of a light-shielding portion, wherein the material (10) is a black resin composition. For a reflective display that displays an image with an ambient light source, it will cause the light to be drunk and the light _ rate is unique, and there is a problem that the bright shirt is good. Japanese Laid-Open Patent Publication No. 2GG8-129599 discloses that the raw material used in the shading portion is changed to a white resin composition, which can improve the light utilization efficiency, but still cannot achieve the requirement of high brightness.
