Abstract
A display device includes: a flexible substrate; a plurality of conductive lines on the flexible substrate; a thin film transistor connected to the plurality of conductive lines; and an organic light emitting element connected to the thin film transistor. As a curvature of an area of the flexible substrate increases, a width or a thickness of each of the conductive lines increases.
Claims10
A display device comprising:
- a flexible display panel configured to display images;
- a housing in which the flexible display panel is rolled to be drawn in or out through an opening;
- and
- a stopper disposed on another side from a rolling shaft of the flexible display panel and having an area greater than an area of the opening,
- wherein:
- the flexible display panel comprises:
- a flexible substrate;
- a conductive line disposed on the flexible substrate;
- a thin film transistor connected to the conductive line;
- and
- a light emitting element connected to the thin film transistor;
- a thickness of the conductive line increases from the stopper toward the rolling shaft;
- and
- the thickness of the conductive line is defined as a size of the conductive line measured along a direction from the flexible substrate toward the conductive line.
