The basic structure of conventional thin-film EL panels is
As shown in the figure, it consists of a front electrode group 2, an EL layer 3, and a back electrode group 4 formed on a glass substrate 1.
The EL layer 3 has a three-layer structure in which a light-emitting layer is sandwiched between insulating layers in a sandwich-like structure. Further, the front electrode group 2 and the back electrode group 4 are composed of striped pattern electrodes (also referred to as electrode lines) that are orthogonal to each other.
This constitutes an X-Y (3×3 dot configuration in the figure) matrix electrode. Electrode external lead terminals 15 and 16 are provided at the ends of each front electrode group 2 and back electrode 4 on the glass substrate 1, respectively, and lead wires (not shown) are electrically connected to these external lead terminals 15 and 16 for moisture proofing. By pulling out the envelope (not shown), the AC power supply 13 is connected to each front electrode group 2 and back electrode group 4 through these lead wires.
By applying an alternating voltage from the EL layer 3, the intersection of these two electrodes, that is, the light-emitting dots 12 of the EL layer 3, is made to emit light.
It is used to display figures, etc.

厚分布などに関する技術的問題から製造できるパ
ネルの大きさはたかだか30×30cm2である。 By the way, manufacturing such thin-film EL panels requires evaporation equipment or sputtering equipment using a vacuum container, so the size of the panels that can be manufactured is limited due to technical issues such as the size of the vacuum container and the thickness distribution of the thin film. The size is at most 30 x 30 cm2 .

という問題点があつた。 For this reason, in order to manufacture large-area graphic display EL panels with a large display capacity, a method of assembling individual thin-film EL panels by joining them together is used. According to the structure of the EL panel, the external lead-out terminals 15 and 16 of the front electrode and back electrode are formed on the peripheral surface of the glass substrate 1, and the envelope is sealed on the substrate, so that the surrounding area of the display area The dead space becomes larger. Therefore, the thin film EL panels could not be connected at the same pitch as the electrode pitch of each EL panel, resulting in a problem of deterioration of display quality.

However, thin film EL configured in this way
The electrode extraction structure of the panel is extremely effective in the case of a single-color EL panel, but as shown in FIG. 8, the front electrode group 2 of the first color is
1. A thin film with a two-color laminated structure formed by sequentially laminating an EL layer 22 of a first color, an intermediate electrode group 23, an EL layer 24 of a second color, and a back electrode group 25 of a second color.
When adopted in an EL panel, the front electrode group 21 of the first color and the back electrode group 25 of the second color overlap, so the front electrode group 21 is provided with a through hole 7 as shown in FIG. When you pull it out to the top,
There was a problem in that the electrode group 21 and the back electrode group 25 were connected, making it impossible to drive each color independently. In addition, in the future, when full-color multicolor laminations with three or more colors are required, there will be problems such as the overlap of this type of electrode group will increase and it will become impossible to draw out individual electrodes that can be driven independently of each other. It was hot.
