Abstract
A display device including a pixel array having a plurality of pixels arranged in a matrix form, each of the pixels including a sampling transistor configured to sample a data potential from a video signal line which is insulated from and intersects a control line in response to the change in potential of the control line, and a light-emitting element configured to emit light at the brightness commensurate with the magnitude of the post-sampling data potential.
Claims12
An apparatus comprising a pixel array having a plurality of pixels, at least one of the plurality of pixels including:
- a light emitting element;
- a pixel capacitor configured to store a potential;
- a first transistor configured to sample a data signal;
- a second transistor configured to drive the light emitting element according to the potential stored in the pixel capacitor;
- a first wiring comprising a lower wiring portion including Molybdenum (Mo) and an upper wiring portion including Aluminum (Al), the upper wiring portion being connected to the lower wiring portion via a plurality of contact holes in an insulating layer therebetween;
- and
- a second wiring including Aluminum (Al),
- wherein,
- the upper wiring portion of the first wiring is at a higher hierarchical level than the lower wiring portion of the first wiring,
- the lower wiring portion of the first wiring extends in a first direction, and
- the second wiring extends in a second direction orthogonal to the first direction.
