- the third anode connection electrode 23 extends in the vertical direction from a region where the light emitting devices 20, 20 ', 20' ', 20' '' are seated to a region where the third anode electrode 20c is located.
- a second extension portion 231 is formed.
- the second anode connection electrode 22 extends from one side of the transparent plate 10 to the other side between the first extension part 211 and the second extension part 231.
- the light emitting device adhering step (S40) is a light emitting device (20, 20 ′, 20 ′) formed by the first anode connection electrode 21, the second anode connection electrode 22, and the third anode connection electrode 23.
- the anode electrodes 20a, 20b, and 20c are positioned to be connected to the first to third anode connection electrodes 21 to 23, and then attached.
- the first anode electrode 20a of the light emitting device 20 is connected to the first extension part 211 extending from the first anode connection electrode 21, and the second anode electrode 20b is connected to the first anode electrode 20b. It is connected to the second anode connection electrode 22, the third anode electrode 20c is bonded to be connected to the second extension portion 231 extending from the third anode connection electrode (23).
- the cathode electrode 20d of the light emitting device 20, 20 ', 20' ', 20' '' is formed of the first anode connection electrode to the third anode connection electrode 21 to the transparent electrode 24 formed first. It is not necessary to form a separate cathode connection electrode because it is in contact with the remaining area other than 23).
- the transparent electrodes connected to the cathode electrodes of the plurality of light emitting devices are commonly formed as described above, the wiring design of the plurality of transparent electrodes connected to the plurality of light emitting devices is very easy and the process is shortened. There is an effect that can be improved productivity.
