ストライプ配列の有機膜を形成するための蒸着マスクは、スリットが長くなるためリブが細長くなっており、剛性が弱い。そのため、高精細化が難しい。これに対して、個々の画素ごとに有機膜を形成すれば、蒸着マスクのスリットが小さくなるためその剛性を上げることができるが、有機膜が小さくなるため、輝度が低下する。   A vapor deposition mask for forming an organic film having a stripe arrangement has a long slit and a long and narrow rib, so that the rigidity is weak. Therefore, high definition is difficult. On the other hand, if an organic film is formed for each pixel, the slit of the vapor deposition mask can be reduced to increase its rigidity. However, since the organic film is reduced, the luminance is reduced.

本発明は、輝度を低下させずに高精細化を図ることを目的とする。   An object of the present invention is to achieve high definition without reducing luminance.

（１）本発明に係る有機エレクトロルミネッセンス表示装置は、第１色の光を発する複数の第１発光層と、第２色の光を発する複数の第２発光層と、第３色の光を発する複数の第３発光層と、を含む有機エレクトロルミネッセンス薄膜と、複数の第１画素電極、複数の第２画素電極及び複数の第３画素電極を含む回路基板と、を有し、前記複数の第１画素電極は、複数の列をなすように並び、前記複数の第２画素電極及び前記複数の第３画素電極は、前記第１画素電極の隣同士の前記列の間に２列で並び、１つの前記第２画素電極及び１つの前記第３画素電極は、それぞれの前記列に交互に並び、前記第１画素電極の隣同士の前記列の間で、前記列の間隔方向に、一対の前記第２画素電極が並び、前記第１画素電極の隣同士の列の間で、前記列の間隔方向に、一対の前記第３画素電極が並び、前記一対の前記第２画素電極と前記一対の前記第３画素電極とは、前記列の前記間隔方向に交互に並び、前記複数の第１発光層は、前記複数の第１画素電極と重なるように配置され、前記複数の第２発光層は、それぞれの前記第２発光層が前記一対の前記第２画素電極と連続的に重なるように配置され、前記複数の第３発光層は、それぞれの前記第３発光層が前記一対の前記第３画素電極と連続的に重なるように配置され、隣り合う１つの前記第１画素電極と１つの前記第２画素電極との間の最短距離Ｄ１２と、隣り合う１つの前記第１画素電極と１つの前記第３画素電極との間の最短距離Ｄ１３と、前記一対の前記第２画素電極の間の最短距離Ｄ２と、前記一対の前記第３画素電極の間の最短距離Ｄ３とは、
Ｄ２＜Ｄ１２
Ｄ２＜Ｄ１３
Ｄ３＜Ｄ１２
Ｄ３＜Ｄ１３
の関係を有することを特徴とする。本発明によれば、第２発光層及び第３発光層がストライプ状になっていないので、蒸着マスクのスリットが長くならず、本発明を用いた表示装置を作製する際の蒸着マスクの剛性が低下しない。また、それぞれの第２発光層が一対の第２画素電極と連続的に重なり、それぞれの第３発光層が一対の第３画素電極と連続的に重なるので、一対の第２画素電極の間の最短距離Ｄ２と、一対の第３画素電極の間の最短距離Ｄ３とを小さくすることができ、第２画素電極及び第３画素電極を大きくすることができる。その結果、表示装置としての輝度を高めることができる。また、１つの第２画素電極及び１つの第３画素電極がそれぞれの列に交互に並んでおり、異なる色を交互に発するようになっているので、１色のラインが形成されないようになっている。こうして、本発明によれば、表示装置の輝度を低下させずにその精細度を高めることができる。なおこれらの効果による本願の当然の効果として、更に本発明を用いた表示装置を作製する際の歩留りの向上によってその表示装置を用いた製品の低コスト化も期待することができる。 (1) An organic electroluminescence display device according to the present invention includes a plurality of first light emitting layers that emit light of a first color, a plurality of second light emitting layers that emit light of a second color, and light of a third color.

The second pixel electrodes are arranged between the adjacent columns of the first pixel electrodes, A pair of the third pixel electrodes are arranged in the interval direction, and the pair of the second pixel electrodes and the pair of third pixel electrodes are alternately arranged in the interval direction of the column, One light emitting layer is disposed so as to overlap the plurality of first pixel electrodes, and each of the plurality of second light emitting layers is configured such that each of the second light emitting layers continuously overlaps the pair of second pixel electrodes. The plurality of third light emitting layers are arranged such that each of the third light emitting layers continuously overlaps the pair of third pixel electrodes, and one adjacent first pixel electrode and 1 the shortest distance between D 12, the shortest distance D 13 between the one adjacent the first pixel electrode and one of the third pixel electrode, the pair of the second pixel between one of the second pixel electrode the shortest distance D 2 between the electrodes, between the pair of the third pixel electrode Is the shortest distance D 3,
D 2 <D 12
D 2 <D 13
D 3 <D 12
D 3 <D 13
It has the relationship of these. According to the present invention, since the second light emitting layer and the third light emitting layer are not in a stripe shape, the slit of the vapor deposition mask does not become long, and the rigidity of the vapor deposition mask when manufacturing the display device using the present invention is increased. It does not decline. Further, each second light emitting layer continuously overlaps with the pair of second pixel electrodes, and each third light emitting layer continuously overlaps with the pair of third pixel electrodes. the shortest distance D 2, can be reduced and the shortest distance D 3 between the pair of third pixel electrode, it is possible to increase the second pixel electrode and the third pixel electrode. As a result, the luminance as a display device can be increased. In addition, since one second pixel electrode and one third pixel electrode are alternately arranged in each column and emit different colors alternately, a line of one color is not formed. Yes. Thus, according to the present invention, it is possible to increase the definition without reducing the luminance of the display device. In addition, as a natural effect of the present application due to these effects, a reduction in cost of a product using the display device can be expected by improving the yield when manufacturing the display device using the present invention.

本実施形態によれば、それぞれの第２発光層１４が一対の第２画素電極３４と連続的に重なり、それぞれの第３発光層１６が一対の第３画素電極３６と連続的に重なっている。したがって、上述した関係が成立するように、一対の第２画素電極３４の間の最短距離Ｄ２と、一対の第３画素電極３６の間の最短距離Ｄ３を小さくすることができる。そのため、最短距離が小さくなった分、第２画素電極３４及び第３画素電極３６を大きくすることができる。その結果、輝度を高めることができる。本実施形態によれば、輝度を低下させずに高精細化を図ることができる。また表示装置を製造する際の歩留りの向上によって本発明による表示装置を用いた製品の低コスト化も期待することができる。 According to the present embodiment, each second light emitting layer 14 continuously overlaps with a pair of second pixel electrodes 34, and each third light emitting layer 16 continuously overlaps with a pair of third pixel electrodes 36. . Therefore, as the relationship described above is satisfied, it is possible to reduce the minimum distance D 2 between the pair of the second pixel electrode 34, the shortest distance D 3 between the pair of third pixel electrode 36. Therefore, the second pixel electrode 34 and the third pixel electrode 36 can be enlarged by the amount that the shortest distance is reduced. As a result, the luminance can be increased.

図３は、本発明の実施形態の変形例１を説明する図である。この変形例では、それぞれの第１発光層１１２、それぞれの第２発光層１１４及びそれぞれの第３発光層１１６は、いずれも丸い平面形状を有する。丸い形状は、これに対応する蒸着マスクの開口を形成しやすい。   FIG. 3 is a diagram illustrating a first modification of the embodiment of the present invention. In this modification, each of the first light-emitting layers 112, each of the second light-emitting layers 114, and each of the third light-emitting layers 116 has a round planar shape. The round shape is easy to form the opening of the vapor deposition mask corresponding to this.

第２発光層１１４の丸い形状に対応して、第２画素電極１３４の第２発光層１１４の外形に対向する輪郭も丸くなっている。同様に、第３画素電極１３６の第３発光層１１６の外形に対向する輪郭も丸くなっている。複数の第１発光層１１２は、１つの第１発光層１１２が１つの第１画素電極１３２と重なるように分離されて形成されている。   Corresponding to the round shape of the second light emitting layer 114, the contour of the second pixel electrode 134 opposite to the outer shape of the second light emitting layer 114 is also rounded. Similarly, the contour of the third pixel electrode 136 opposite to the outer shape of the third light emitting layer 116 is also rounded. The plurality of first light emitting layers 112 are formed separately so that one first light emitting layer 112 overlaps with one first pixel electrode 132.

１つの第２発光層１１４と重なる一対の第２画素電極１３４は、それぞれの第１画素電極１３２の、列に直交する方向（図３で左右方向）に隣り合う位置から、列に沿った方向（図３で上下方向）にずれた位置（すなわち斜め右又は斜め左）に配列されている。   A pair of second pixel electrodes 134 overlapping with one second light emitting layer 114 is a direction along the column from a position adjacent to each of the first pixel electrodes 132 in a direction orthogonal to the column (left-right direction in FIG. 3). They are arranged at positions shifted in the vertical direction in FIG. 3 (that is, diagonally right or diagonally left).

同様に、１つの第３発光層１１６と重なる一対の第３画素電極１３６は、それぞれの第１画素電極１３２の、列に直交する方向（図３で左右方向）に隣り合う位置から、列に沿った方向（図３で上下方向）にずれた位置（すなわち斜め右又は斜め左）に配列されている。本変形例のその他の内容は、上記実施形態で説明した内容が該当する。   Similarly, the pair of third pixel electrodes 136 that overlap with one third light emitting layer 116 is arranged in a column from a position adjacent to each of the first pixel electrodes 132 in a direction orthogonal to the column (left and right direction in FIG. 3). They are arranged at positions (that is, diagonally right or diagonally left) that are shifted in the direction along (the vertical direction in FIG. 3). The other contents of this modification correspond to the contents described in the above embodiment.

本実施形態によれば、第１発光層１１２は正方配置のドットの開口形状を有するマスクを用いて蒸着されるが、第２発光層１１４及び第３発光層１１６は千鳥配置のドットの開口形状を有するマスクを用いて蒸着される。このように第１発光層１１２、第２発光層１１４及び第３発光層１１６の蒸着マスクはストライプ状になっていないので、これらを形成するときに使用する蒸着マスクのスリットが長くならず、蒸着マスクの剛性が低下しない。加えて第２発光層１１４及び第３発光層１１６の蒸着マスクの開口は、それぞれ第２画素電極１３４及び第３画素電極１３６が２個に開口が１個の割合で設けられているため、画素電極の半分の数で十分である。このように第２発光層１１４及び第３発光層１１６の蒸着マスクは開口が画素数の半分で済むため、本実施形態は蒸着マスクの剛性向上には更に有利である。   According to the present embodiment, the first light-emitting layer 112 is deposited using a mask having a square-shaped dot opening shape, while the second light-emitting layer 114 and the third light-emitting layer 116 are staggered dot opening shapes. Vapor deposition using a mask having As described above, since the vapor deposition masks of the first light emitting layer 112, the second light emitting layer 114, and the third light emitting layer 116 are not striped, the slits of the vapor deposition mask used for forming these do not become long. Mask rigidity does not decrease. In addition, the openings of the evaporation masks of the second light emitting layer 114 and the third light emitting layer 116 are provided with a ratio of one opening to two each of the second pixel electrode 134 and the third pixel electrode 136. Half the number of electrodes is sufficient. As described above, since the evaporation masks of the second light emitting layer 114 and the third light emitting layer 116 need only have half the number of pixels, this embodiment is further advantageous for improving the rigidity of the evaporation mask.
