Abstract
An OLED display panel is provided which can control the problem of shedding even in high definition panels. Metal wiring 5 which conducts with an earth line of a flexible printed substrate 15 is provided on a substrate 1. A display area 2 comprised from a plurality of OLED elements is provided at the center of the substrate 1 and four low resistance metal films 3 are provided along each of four edges of the display area 2 on a surface of insulation films 8, 10 at the periphery of the display area 2. Among these, one low resistance metal film 3 conducts with the metal wiring 5 via a contact 3a.
Claims16
A display device comprising:
- a substrate on which a display area including a plurality of OLED elements and a peripheral area surrounding the display area are arranged;
- a wire in the peripheral area;
- a first insulation layer above the wire;
- a second insulation layer above the first insulation layer;
- a metal film above the second insulation layer;
- and
- a sealing film above the metal film, wherein
- the first insulation layer has a first contact hole in the peripheral area,
- the second insulation layer has a second contact hole in the peripheral area,
- the metal film and the wire are electrically connected via the first contact hole and the second contact hole,
- the metal film, the wire and the first contact hole overlap with each other, and
- the first insulation layer and the second insulation layer are in contact with each other in the peripheral area.
A display device comprising:
- a substrate on which a display area including a plurality of OLED elements and a peripheral area surrounding the display area are arranged;
- a wire in the peripheral area;
