図4(A),(B)は、この切断部Aを形成する前の平面構成(A)および図4(A)のI−I線における断面構成(B)をそれぞれ表したものである。配線25Cは、例えば隣り合う2本の直線状の配線25C1および配線25C2により構成されており、これら配線25C1,25C2の間には短絡部25Xが生じている。図1は、この短絡部25Xによって配線25C1,25C2が接合された位置に切断部Aが形成された構造を表している。 FIGS. 4A and 4B respectively show a planar configuration (A) before the cutting portion A is formed and a cross-sectional configuration (B) taken along line II in FIG. 4A. Wiring 25C, for example two is constituted by linear wiring 25C 1 and the wiring 25C 2 adjacent, short-circuit portion 25X has occurred between the wiring 25C 1, 25C 2. FIG. 1 shows a structure in which a cut portion A is formed at a position where the wires 25C 1 and 25C 2 are joined by the short-circuit portion 25X.

前述のように、線欠陥や輝点は表示装置の見栄えを大きく損なう重大な不良であり、例えば信号線120Aと電源ライン(GND)とが短絡した場合には線欠陥不良が発生する。この不良を救済するためには、例えば信号線120AとGNDとの短絡部Xを切断(切断箇所A)するか、短絡部X前後のGNDを切断(切断箇所B)して短絡部Xと共に信号線120Aの一部とし、対応する発光素子10Wを電気的にフローティングな状態として黒点化する方法が考えられる。これら切断箇所A,Bは、それぞれ図3,11におけるO−O線(切断箇所A)、P−P線,Q−Q線(切断箇所B)である。 As described above, line defects and bright spots are serious defects that greatly impair the appearance of the display device. For example, when the signal line 120A and the power supply line (GND) are short-circuited, a line defect defect occurs. In order to remedy this defect, for example, the short circuit portion X between the signal line 120A and GND is cut (cutting point A), or the GND before and after the short circuit portion X is cut (cutting point B) and a signal is output together with the short circuit portion X. A method can be considered in which a part of the line 120A is used, and the corresponding light-emitting element 10W is made into an electrically floating state to be blackened. These cut points A, B are respectively diagrams 3, O-O line in 11 (cut part A), a line P-P, Q-Q line (cut part B).

なお、黒点化する際には、GND等の共通電位線が接続されているコンタクトホールおよび陽極または陰極として画素駆動回路140と発光素子10Wとを接続するコンタクトホール(図10,11中の■)を各接続先から切り離す必要がある。コンタクトホールを切り離す方法としては、図13A,図13Bに示したように、コンタクト領域にレーザ光を照射して開口Pを形成(図13A)したのち、この開口P内に有機樹脂等の絶縁材料を埋設(図13B)すればよい。図13Aようにレーザ光によって開口Pを形成する際にコンタクトホールの下層に配線層21,25,27やチャネル層23があると層間短絡が発生するため駆動側のコンタクトホールについては層間短絡が生じた配線を走査線120Aから切り離す。また、走査線120Aの切り離し部分と共通電位線のコンタクトホール下については層間短絡を回避するために配線層21,25,27またはチャネル層23の少なくとも一方が切断箇所に存在しないようなレイアウトとする。これにより、発光素子10Wは電気的にフローティング状態となって黒点化する。 In addition, when making a black spot, a contact hole to which a common potential line such as GND is connected and a contact hole to connect the pixel driving circuit 140 and the light emitting element 10W as an anode or a cathode ( ■ in FIGS. 10 and 11) Must be disconnected from each destination. As a method of separating the contact hole, as shown in FIGS. 13A and 13B, the contact region is irradiated with laser light to form an opening P (FIG. 13A), and then an insulating material such as an organic resin is formed in the opening P. May be embedded (FIG. 13B). When the opening P is formed by laser light as shown in FIG. 13A, if the wiring layers 21, 25, 27 and the channel layer 23 are present in the lower layer of the contact hole, an interlayer short circuit occurs. Separate the wiring from the scanning line 120A. Further, in order to avoid an interlayer short circuit, a layout in which at least one of the wiring layers 21, 25, 27 and the channel layer 23 does not exist at the cut portion is provided for the part separated from the scanning line 120 A and the contact hole of the common potential line. . As a result, the light emitting element 10W becomes electrically floating and becomes a black spot.
