Abstract
A flexible display device includes: a flexible substrate having a lower substrate including a prominence pattern, a barrier layer pattern on the prominence pattern, and a planarization film; a gate line on the flexible substrate; a data line crossing the gate line with having a gate insulation film therebetween to define a pixel region; a thin film transistor formed at an intersection of the gate line and the data line; and a passivation layer on the flexible substrate including the thin film transistor. With this configuration, the flexible substrate and the flexible display device can be enhanced by preventing property deterioration of the elements due to bending stresses.
