Abstract:
1. A display module, comprising: a substrate; the substrate comprising; a plurality of scanning lines, a plurality of data lines and a plurality of current supply lines each of which intersects the plurality of scanning lines, formed in a sealing section thereon; a plurality of pixels formed corresponding to the intersections of the plurality of scanning lines and the plurality of data lines, and forming a display section; each of the plurality of pixels comprising a pixel circuit comprising a first active element turned on by a scanning signal supplied from one of the plurality of scanning lines to acquire a data signal supplied from one of the plurality of data lines, a data holding element holding the data signal acquired by the first active element, a light emitting device, and a second active element being turned on in accordance with the data signal held by the data holding element to supply a current from one of the plurality of current supply lines to let the light emitting device emit light; the light emitting device comprising a first electrode layer receiving the current from the second active element, an organic light emitting layer formed over the first electrode layer, and a second electrode layer formed over the organic light emitting layer; a current supply bus layer electrically connected to the current supply lines and electrically connected to an outside of the sealing section; a second electrode connection layer electrically connected to the second electrode layer and electrically connected to an outside of the sealing section; wherein at least one part of the current supply bus layer in the sealing section is formed over insulating films below a passivation film; wherein at least one part of the second electrode connection layer in the sealing section is formed between the section and the current supply bus layer, and formed over the insulating films below the passivation film; and wherein the second electrode layer and the second electrode connection layer are electrically connected by a contact hole formed in the passivation film.
