Abstract

According to an aspect of the present invention, there is provided a capacitive device, including: a first electrode, including: a first region and a second region, having areas separated from each other; and a first connection bridge, in the first region and the second region The first region and the second region are electrically connected therebetween; a second electrode is provided opposite to the first electrode; and a dielectric film is formed between the first electrode and the second electrode.

Description

technical field [0001] The present invention relates to a capacitive device and a display device including the capacitive device. Background technique [0002] The flat panel display device includes an organic light-emitting display device and a liquid crystal display device, etc., which apply scan signals and data signals to device parts including a plurality of thin film transistors and capacitors through scan lines and data lines, and transmit signals applied to the device parts To the light emitting device electrically connected to the device part, thereby presenting an image. [0003] A capacitor included in a display device includes: a first electrode; a second electrode; and an insulating layer functioning as a dielectric film between the first electrode and the second electrode. When the dielectric film is damaged by contamination sources such as particles during the manufacturing process, a short circuit occurs between the first electrode and the second electrode, ...
