Description of the Invention: [Technical Field] The present invention relates to a four-color full-color organic electroluminescence display device, which can not only effectively improve the transmittance and color saturation of each color light source, but also reduce the consumption. Electricity and people who increase production yield. [Prior Art] Since the formation of organic electroluminescence devices (OLEDs) by CWTang and SAVanSlyke of Kodak Company in 1987 by vacuum evaporation, the industry has been focusing on research related to organic electroluminescent display devices. And development, how to achieve the full color display effect and the improvement of the old full color technology, in order to become the key to the success of the development of organic electric display devices, the most common production method and structure to achieve full color display function There are two main types: 1. Set the organic electroluminescent elements that can produce red (R), green (G), and blue (B) colors separately (Side by Side), and mix the three color lights in appropriate proportions. Matches to produce a full color display. However, during the manufacturing process, since the red, green, and blue luminescent materials must be separately vapor-deposited, and the mask opening of each pixel is only ten micrometers, the difficulty in mask alignment is improved. 2. An organic electroluminescent element having at least one white light source is provided, and a color filter which is technically sophisticated is used. Through the use of color filters to achieve the purpose of filtering, white light source, and thus produce full color display effect. The setting method is relatively simple compared with the method of separately evaporating red, green and blue luminescent materials. However, the light source of each color light source produced by the organic electroluminescent device manufactured by the method has poor transmittance to the color filter, and is liable to cause poor color saturation of each color light, insufficient display brightness, and power supply. The problem of waste and other issues. The organic electroluminescent elements which can produce the three primary colors are independently arranged, as shown in Fig. 1. An organic light-emitting layer 23 is disposed on a substrate 11, and the organic light-emitting layer 23 includes a first organic light-emitting layer 231, a second organic light-emitting layer 233, and a third organic light-emitting layer 235. The first light source S generated by the organic light-emitting layer 23, the second light source S2 and the third light source S3 are respectively a red light source, a green light source and a blue light source, which can be achieved by mixing and matching the light sources of appropriate colors. The purpose of the full-color display of the electromechanical excitation light display device 200. However, the organic light-emitting layer 23 disposed above the substrate 11 is completed through a mask alignment and evaporation process. Among them, if there is an error in the mask alignment, the setting of the organic light-emitting layer 23 will be directly affected. For example, if the mask alignment is inaccurate during the evaporation process of the second organic light-emitting layer 233, the position of the second organic light-emitting layer 233 is shifted, and an error region 239 is generated. Since the second organic light-emitting layer 233 is not present on the error region 239, the error region 239 will not produce the second light source S2. The area of action of the second organic light-emitting layer 233 is reduced, which affects the luminance of the second light source S2 and the display quality of the display device. [Abstract] δ 200814846 To this end, how to design a novel four-color full-color organic electroluminescent display device for the problems encountered by the above-mentioned conventional techniques, and propose an effective solution to the problem of mask alignment accuracy It can achieve the increase of the transmittance and the increase of the color saturation of the electroluminescent display device, which is the focus of the invention.

The first light source si generated by the stacked first organic light-emitting layer 43i and the third organic light-emitting layer 435 will penetrate the first color photoresist 351 and be filtered to generate a first color light L1. The second light source 82 generated by the stacked second organic light-emitting layer 433 and the third organic light-emitting layer 435 will penetrate the second color photoresist 353 and be filtered to generate a second color light L2. The second light source S3 generated by the third organic light-emitting layer 435 can penetrate the third color photoresist 355 and the fourth color photoresist 357, and filter to generate a third color light L3 and a fourth color light L4. In one embodiment, the light sources generated by the first organic light-emitting layer 431 and the second organic light-emitting layer 433 may respectively select one of red, green or blue light sources. Of course, other colored light sources may also be selected, but, The light source of the 11 200814846 generated by the organic light-emitting layer 431 and the second organic light-emitting layer 433 needs to be different colors. For example, the first organic light-emitting layer 431 generates a red light source ¥, and the light source generated by the second organic light-emitting layer 433 can be selected as green or When the first organic light-emitting layer 431 generates a green light source, the light source generated by the second organic light-emitting layer 433 may select a red or blue light source, and the third organic light-emitting layer 435 may generate a white light source. The colors of the light sources generated by the first organic light-emitting layer 431 and the second organic light-emitting layer 433 are required to match the colors used by the first color photoresist 351 and the second color photoresist 353, for example, when the first organic light-emitting layer 431 and the second When the organic light-emitting layer 433 generates a red light source and a green light source, respectively, the first color photoresist 351, the second color photoresist 353, and the third color photoresist 355 are respectively a red photoresist, a green photoresist, and a blue photoresist. The four color photoresist 357 is a light transmitting portion or a hollow portion. The first color light u, the second color light L2, the third color light L3, and the fourth color light L4 filtered by the first color filter layer 35 are respectively a red color, a green light, a blue light, and a white light. Wherein, the mixing of the first color light u, the second color light L2 and the third color light L3 can achieve the purpose of full color display of the organic electroluminescent display device 400, and the fourth color light L4 can be promoted to the organic electric excitation. The display color gradation and display brightness of the light display device 400. The electromechanical excitation light display device 400 is a Bottom-Emission organic electroluminescence display device. The first color filter layer 35 is a device that allows only a light source of a specific wavelength range to pass therethrough, and thereby achieves the purpose of color filter. For example, the first color photoresist 351 passes only a light source having a wavelength range of 64 〇 nm to 770 nm, and the first color light 351 is a white light source and penetrates the first color photoresist 351. The resistor 351 filters and blocks other color light sources with wavelengths ranging from 64 〇 to 12 200814846 770 nm. The color light of the 光 color resist 351 has a wavelength range of 640 nm to 77 〇n, which is a red light source that can be felt by the naked eye, thereby achieving a plurality of light, @'. However, at the same time of light color filtering, the color light source with a wavelength of 640nHl~~~77〇n will be filtered by the first color photoresist 351, and the source transmittance is only 25% to 35%. Relatively, it will decrease _ Qi ~ will have to first % 泠, if the first color resist 351 is red resist, it will be <.
許色光通過之波長範圍係如前述所言是在64 770nm。則第一彩色光阻351對一紅色光源（例如、、办〜 吸長分& 範圍係為650nm〜760nm)而言將具有一良好的穿遷率怖 光源穿透率將可達到70%以上。 其 藉由第三有機發光層435之設置，可克服毁置第_ 發光層431及第二有機發光層433時，因遮罩對位的、有 所造成的良率損失。例如，請參閱第2 B圖，當笫-二^ 中〜有機 發光層433於遮罩對位程序進行時有偏移之情形發生，將 形成一誤差區域439。然而，第二彩色光阻353之垂直延 伸位置上尚設置有第三有機發光層435,使得偏移之誤差 區域439上將會存在第三有機發光層435。當第三有機發 光層435所產生之第三光源S3係為一白色光源時，第三 光源S3將會經由第一電極41穿透第二彩色光阻353並過 遽產生相同的第二色光L2。 因此，藉由第三有機發光層435之設置，將可克服設 置第一有機發光層431及第二有機發光層433時，因遮罩 對位的誤差所造成的良率損失。即便第一有機發光層43j 13 200814846 及/或第二有機發光層433於遮罩對位 會影響有機電激發光顯示裝置 h 。、差產生，亦不 產品良率之提昇。而第一有機二示品質，而有利於 層433之設置，可有效提高^光層431及第二有機發光 光源的穿透率及色彩飽和度，激發光顯示裝置之各色The wavelength range through which the chromatic light passes is as described above at 64 770 nm. Then, the first color photoresist 351 will have a good embedding rate for a red light source (for example, , the length of the absorption and the range of 650 nm to 760 nm), and the transmittance of the light source can reach 70% or more. . By the arrangement of the third organic light-emitting layer 435, the loss of yield due to the alignment of the mask when the first light-emitting layer 431 and the second organic light-emitting layer 433 are destroyed can be overcome. For example, referring to Fig. 2B, when the 有机-二^~ organic light-emitting layer 433 is offset when the mask alignment process is performed, an error region 439 is formed. However, the third organic light-emitting layer 435 is disposed at a vertical extension of the second color photoresist 353 such that a third organic light-emitting layer 435 will be present on the offset error region 439. When the third light source S3 generated by the third organic light-emitting layer 435 is a white light source, the third light source S3 will penetrate the second color photoresist 353 via the first electrode 41 and generate the same second color light L2. . Therefore, by the arrangement of the third organic light-emitting layer 435, the yield loss due to the error of the mask alignment can be overcome when the first organic light-emitting layer 431 and the second organic light-emitting layer 433 are disposed. Even if the first organic light-emitting layer 43j 13 200814846 and/or the second organic light-emitting layer 433 are aligned in the mask, the organic electroluminescent display device h is affected.
