Description

Can improve the organic electroluminescence display device and method of manufacturing same of display level
Technical field
The present invention relates to a kind of organic electroluminescence display device and method of manufacturing same that improves display level, can effectively improve the color range of light source penetrance and demonstration, simplify processing step and improve the production yields.
Background technology
In numerous displays, how to reach the technology key of this display development success or not often, and with regard to organic electroluminescence display device and method of manufacturing same (OLED), reaching the modal method of full-color Presentation Function there are following two kinds with full-color display effect:
1, three primary colors independence picture element is luminous: can produce red (R), green (G) respectively, blue (B) trichromatic organic electroluminescence assembly independently is provided with, and these three kinds of coloured light are produced full-color display effect with the proper proportion mix and match.
Yet, because this organic electroluminescence display device and method of manufacturing same need produce different color light via repeatedly evaporation and mask steps when making organic light-emitting units, not only comparatively loaded down with trivial details on production process, and the requirement to accuracy when evaporation or shielding contraposition also improves relatively, easier so and reduction product yield and the relative cost of manufacture that improves.
2, colored filter (Color Filter): be provided with at least one organic electroluminescence assembly that sends white light source, the skillful colored filter of collocation operation technique, by the use of colored filter purpose, and therefore produce full-color display effect with the light color filtering that reaches white light source.
The general using colored filter carries out the organic electroluminescence display device and method of manufacturing same of light color filtering, as shown in Figure 1, colored filter 10 mainly is that a transparency carrier 11 is provided with a black matrix" 13 (BlackMatrix), and be provided with a chromatic filter layer 15 with light color filtering function in transparency carrier 11 upper surfaces that are not provided with black matrix" 13, include the first colored photoresist (photoresistance) 151 (G), the second colored photoresist 153 (B) and the 3rd colored photoresist 155 (R).The selectable planarization layer 17 (Over Coat claims coat again) or that is provided with blocks layer above black matrix" 13 and chromatic filter layer 15, to help the carrying out of subsequent technique.
In addition, the lower electrode 21 of organic electroluminescence assembly 20 is directly to be arranged at the upper surface that blocks layer or planarization layer 17, and be provided with an organic light-emitting units 23 and a subtend electrode 25 in regular turn in the upper surface of lower electrode 21, operating current conducting by lower electrode 21 and counter electrode 25, make organic light-emitting units 23 project a white light source S, this white light source S is after penetrating chromatic filter layer 15, to carry out the action of a light color filtering, and become green, blue, red three primary colors L1, L2, L3, and matched combined is to reach the purpose of organic electroluminescence display device and method of manufacturing same 200 full-color demonstrations.
Use by colored filter 10, a kind of organic light-emitting units 23 that produces white light source S of 200 needs of this organic electroluminescence display device and method of manufacturing same, therefore also only need less evaporation process to get final product the accurate contraposition degree of difficulty in the time of effectively to reduce evaporation or shielding.Yet white light source S is not good to the light source penetrance of chromatic filter layer 15, and then influences the luminosity and the photochromic saturation of this organic electroluminescence display device and method of manufacturing same 200, thereby can't effectively improve its luminous mass.
