A pixel in the panel includes sub-pixels 100a, 100b, and 100c. The sub-pixel 100a is defined by banks 105a and 105b. The sub-pixel 100b is defined by banks 105b and 105c. The sub-pixel 100c is defined by banks 105c and 105d. Organic light-emitting layers are formed in sub-pixels by, for each pixel, applying ink to the sub-pixels 100a, 100b, and 100c in the stated order and drying the applied ink. With regard to a sidewall 105aa of the bank 105a, sidewalls 105ba and 105bb of the bank 105b, and a sidewall 105cb of the bank 105c, inclination angles of the sidewalls satisfy relationships: inclination angle θaa and inclination angle θba are equal, and inclination angle θcb is larger than inclination angle θbb.
