Therefore, when viewed as the entire CF, the CF layer becomes a convex portion, and the portion of the adjacent CF layer formed on the upper surface of the partition wall. The gap portion between them is a recess.
- an auxiliary electrode for supplying voltage to the cathode is arranged for each pixel on the EL substrate side in order to reduce variation in luminance due to voltage drop at the cathode. Therefore, in CF, the area corresponding to the area where the auxiliary electrode is formed (hereinafter referred to as “inter-pixel area”) is compared with the area corresponding to the area between sub-pixels (hereinafter referred to as “inter-sub-pixel area”). Thus, the partition walls are formed wide.
