According to an embodiment, the light emitting element OLED includes a first electrode E1, an emission layer EL, and a second electrode E2. The first electrode E1 is disposed on the third insulation layer 30, and penetrates through the third insulation layer 30 to connect to the transistor TR. The fourth insulating layer 40 is disposed on the third insulating layer 30 and covers an edge portion of the first electrode E1, exposing a center portion of the first electrode E1. The emission layer EL covers the center portion of the first electrode E1 exposed by the fourth insulation layer 40. The emission layer EL includes a light emitting material that generates light in correspondence to a potential difference. For example, the emission layer EL may include an organic light emitting material or a quantum dot. The second electrode E2 is disposed on the emission layer EL and the fourth insulating layer 40. The second electrode E2 is formed on the front surface of the display area DA.

According to an embodiment, the light emitting element OLED generates and emits light corresponding to a potential difference between a data signal provided to the first electrode E1 through the transistor TR and a power supply voltage, such as a ground voltage, provided to the second electrode E2.

According to an embodiment, a conductive pattern CP1 connects the data lines DL and the pad PD. The conductive pattern CP1 includes a plurality of line patterns that extend along the second direction D2 and are separated from each other along the first direction D1.
