Summary:PROBLEM TO BE SOLVED: To provide a display device having high display quality.SOLUTION: In a display device including a plurality of pixels, adjacent pixel electrodes are formed over different insulating layers. Accordingly, when seen in a plan view, the adjacent pixel electrodes can be close to each other without constraints of design rules. Openings (light-emitting regions) of the adjacent pixels can be close to each other, leading to an improvement in graininess. The use of a step provided between the adjacent pixel electrodes can increase the resistance of an EL layer across the adjacent pixels to reduce crosstalk.SELECTED DRAWING: Figure 1 【課題】表示品位が良好な表示装置を提供する。【解決手段】複数の画素を有する表示装置において、隣接する画素電極を異なる絶縁層上に設ける。これにより、平面図で見た場合に、デザインルールの制約を受けることなく隣接する画素電極同士を近づけることができる。隣接する画素の開口部（発光領域）を近づけることができるため粒状感が改善される。隣接する画素電極の段差を利用することにより、隣接する画素にまたがる領域のＥＬ層を高抵抗化して、クロストークを抑制する。【選択図】図１
