[0189] Next, use Figure 12 Modification 1 of the manufacturing method of the display device 1 will be described. Figure 12 express with Figure 9 (c)~ Figure 10 The process corresponding to the process shown in (a).

[0190] Such as Figure 12 As shown, after the bank material layer 1050 is laminated and formed on the hole injection transport layer 104, the mask 503 is disposed thereon. The mask 503 is provided with light-transmitting portions 503a1, 503a2, 503b, 503c, 503d1, and 503d2. The light-transmitting parts 503a1 and 503a2 are provided corresponding to the parts where the banks 105a are to be formed, the light-transmitting parts 503b and 503c are provided corresponding to the parts where the banks 105b and 105c are to be formed, and the light-transmitting parts 503d1 and 503d2 are provided corresponding to the parts where the banks 105d are to be formed. set for the location.

[0191] In the method of manufacturing the display device 1 according to Modificatio...

Deformed example 2

[0198] Next, use Figure 13 and Figure 14 Modification 2 of the manufacturing method of the display device 1 will be described. Figure 13 and Figure 14 express with Figure 9 (c)~ Figure 10 (b) The corresponding process of the process shown.

[0199] Such as Figure 13 As shown in (a), after the bank material layer 1050 is laminated and formed on the hole injection transport layer 104 , the mask 504 is disposed thereon. In the mask 504 , openings 504 a , 504 b , 504 c , and 504 d are provided corresponding to the respective locations where the banks 105 are to be formed.

[0200] The openings 504d and 504c are formed to have the same width as the openings 501b and 501c of the mask 501 used in the manufacturing method of the above-described embodiment.

[0201] On the other hand, banks 105a, 105d are formed between the planned sub-pixel region 1000a and the planned non-pixel region 1000d, and between the planned sub-pixel region 1000c and the planned non-pixel region...

Abstract

A pixel part is constituted so as to contain three sub-pixels (100a - 100c). Furthermore, non-pixel parts (100d, 100e) are disposed between adjacent pixel parts. A bank (105a) divides an organic light emitting layer of the sub-pixel (100a) and the non-pixel part (100d), and likewise, a bank (105d) divides an organic light emitting layer of the sub-pixel (100c) and the adjacent non-pixel part (100e). In addition, a bank (105b) divides the organic light emitting layer of the sub-pixel (100a) and an organic light emitting layer of the sub-pixel (100b), and a bank (105c) divides an organic light emitting layer of the sub-pixel (100b) and the organic light emitting layer of the sub-pixel (100c). Here, the angle of inclination ?aa of a surface part (105aa) on the sub-pixel (100a) side of the bank (105a) and the angle of inclination ?dc of a surface part (105dc) on the sub-pixel (100c) side of the bank (105d) are set to an angle greater than the other angles of inclination (?ba, ?bb, ?cb, ?cc).

Description

[0001] technology area [0002] The present invention relates to an organic light-emitting panel, a manufacturing method thereof, and an organic display device. Background technique [0003] In recent years, research and development of display devices using the electroluminescence phenomenon of organic materials has progressed. In this display device, each pixel portion is configured to have an anode electrode, a cathode electrode, and an organic light-emitting layer interposed between the anode electrode and the cathode electrode. In addition, in driving the display device, holes are injected from the anode electrode, electrons are injected from the cathode electrode, and the holes and electrons are recombined in the organic light-emitting layer to emit light. [0004] The organic light-emitting layers of adjacent pixel portions are partitioned by partition walls (banks) made of an insulating material. For the formation of the organic light-emitting layer, for example, ink ...
