Problems solved by technology

However, the above-mentioned method is not only relatively limited in the change range of the transmittance of the film that can be obtained only by adjusting the content and thickness of the pigment, but also cannot obtain the actual anti-reflection film due to the decrease of the pattern adhesion force or the increase of residue. Transmittance at the required level

[0212]

[0213] Using the photosensitive resin compositions of Production Examples 2, 4, and 5, two layers were laminated so as to include regions as shown in Table 3, respectively, to form films of Examples 1 to 4. In addition, a film of a comparative example was formed by laminating a photosensitive resin composition containing carbon black to produce the red pigment of Example 2 with a thickness of 1.0 μm. The thickness, OD and reflectance of this film were measured.

[0214] As described above, the film formation process at the time of lamination is as follows.

[0215] Films were formed using the photosensitive resin compositions of Production Examples 1 to 5 so that a thin film having a thickness of 1 to 2 μm on the post-POB basis could be obtained using a spin coater. Pre-drying was carried out for 2 minutes on a 90° C. hot plate (Hotplate). The board|substrate was exposed to 40mJ with an exposure machine, and pattern formation was performed, respectively, with an i...

Abstract

The present invention relates to an optical filter of an organic light emitting device and a method of manufacturing the same. The optical filter includes a light-transmissive region including an R, G, and B color filter single-layer structure and a laminate of color filters of two or more different color light using a low temperature curable photosensitive resin composition that can be used for the purpose of preventing reflection of an OLED Shielding region including the structure can replace the existing polarizing film, and also has an excellent antireflection performance.

Description

technical field [0001] The present invention relates to an optical filter of an organic light emitting device capable of replacing a polarizer and not including a black matrix layer, and an organic light emitting device including the same. Background technique [0002] As the flat panel display device, a liquid crystal display device (LCD: Liquid crystal display device), an organic light emitting display device (OLED: Organic light emitting display device), and the like are widely used. Among them, organic light-emitting display devices in particular have the advantages of low power consumption, response speed, high color reproduction rate, high brightness, and wide viewing angle. [0003] In the case of the organic light-emitting display device described above, a polarizer is used to block light reflected from the panel by incident external light, but there is a disadvantage that the above-mentioned polarizer is not suitable due to insufficient bendability if it is to be ap...
