As shown in the illustration (b) of FIG. 1, the first metal film 22T and the second metal film 25T are formed in the same size and sandwich each analysis EL layer 24T of the analysis sub-pixels TR, TG, and TB. Moreover, a ground wire GW is formed of the first metal film 22T, and lead out of the sealing layer 6 over an edge side 6E of the sealing layer 6.
The illustration (b) of FIG. 1 shows an example that the first metal film 22T is provided in common among the analysis sub-pixels TR, TG, and TB. However, the disclosure shall not be limited to such an example. For example, the first metal film 22T may be provided for each of the analysis sub-pixels TR, TG, and TB. In such a case, three ground wires GW are each provided to correspond to one of the analysis sub-pixels TR, TG, and TB.
Furthermore, in the above description, the illustration (b) of FIG. 1 shows an example that the first metal film 22T and the second metal film 25T are formed into the same shape. However, the disclosure shall not be limited to this example. The first metal film 22T and the second metal film 25T may be formed into different shapes.
