First rib layers made of an inorganic material are formed in first frame regions of a first glass substrate. First resin layers are formed in first product regions after the first rib layers are formed. First functional layers which include light emitting element layers as a result of luminance of each of unit pixels forming an image being controlled and sealing layers covering the light emitting element layers are formed on the first rib layers and the first resin layers. The first rib layers and the first functional layers are cut along lines passing through the first frame regions while avoiding the first product regions in order to separate the first product regions from each other. In the step of cutting the first rib layers and the first functional layers, the first rib layers and the sealing layers are cut.

Method of fabricating display device ring shape rib layer

A glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack is required to be formed uniformly. Applying a force to resist the rotating force of the wheel makes it possible to form a uniform crack even when a projection is present on the glass. This improves glass cutting yield.
