Display device and method of manufacturing the same

摘要

A display device is provided. The display device includes a substrate including a pixel region, a thin film transistor formed on the substrate, a light blocking member formed at a boundary of the pixel region, and a pixel electrode formed in the pixel region, the pixel electrode connected to the thin film transistor. The display device also includes a common electrode formed on the light blocking member, the common electrode spaced apart from the pixel electrode with a microcavity interposed between the common electrode and the pixel electrode, and a roof layer comprising a color filter formed on the common electrode. The display device further includes an opening formed in the common electrode and the roof layer to expose a portion of the microcavity, a liquid crystal filling the microcavity, and an overcoat formed on the roof layer to cover the opening and seal the microcavity for each pixel region.

1. A method of manufacturing a display device, comprising:
forming a thin film transistor on a substrate, the substrate including a pixel region; forming a light blocking member at a boundary of the pixel region; forming a pixel electrode in the pixel region, the pixel electrode connected to the thin film transistor; forming a sacrificial layer on the pixel electrode and the light blocking member; ashing the sacrificial layer; forming a common electrode on the sacrificial layer and the light blocking member; forming a roof layer on the common electrode, the roof layer comprising a color filter; forming an opening in the common electrode and the roof layer; forming a microcavity by removing the sacrificial layer through the opening; injecting a liquid crystal to fill the microcavity through the opening; and forming an overcoat to seal the opening.
