A part of a capacitor is disposed in the horizontal direction of a luminescent region so as to secure a gap in the horizontal direction of the luminescent region. As the distance between adjoining pixels in the horizontal direction is thus secured, color mixing is unlikely, even when an error is caused in positioning a metal mask when forming luminescent layers by evaporation. Further, a portion of the capacitor or TFTs is also disposed in the vertical direction of the luminescent region. Therefore, enhanced color purity can even be achieved for pixels adjoining one another in the column direction in the delta pixel arrangement.
