Abstract: A display panel includes a base layer bendable with respect to a virtual axis, a driving element layer including a transistor, and a light emitting element layer including a first electrode, emission layers disposed on the first electrode, and second electrodes disposed on the emission layers. One of the second electrodes is electrically connected to the transistor. The first electrode includes first sub electrodes overlapping the emission layers and a connection pattern layer that electrically connects the first sub electrodes. The connection pattern layer includes a first connection pattern layer that electrically connects the first sub electrodes in a first direction parallel to the virtual axis, and a second connection pattern layer that electrically connects the first sub electrodes in a second direction intersecting the first direction. The first connection pattern layer has a density greater than that of the second connection pattern layer.
