Electronic device and display panel

An electronic device comprising:

• a display panel including a display region having a first region and a second region which has a lower transmittance than the first region, and a non-display region adjacent to the display region;
• and
• an electronic module disposed under the display panel, and overlapping the first region,
• wherein the display panel includes:
• a base substrate having a first base layer, a second base layer, and a first barrier layer disposed between the first base layer and the second base layer and overlapping the display region and the non-display region,
• a light-emitting element disposed on the base substrate and overlapping the display region,
• a pixel circuit disposed in the second region,
• a connection line connected to the light-emitting element in the first region and connected to the pixel circuit in the second region, and
• an encapsulation layer disposed on the light-emitting element and covering the light-emitting element, and
• wherein the first barrier layer includes:
• a (1-1)-th barrier layer disposed on the first base layer and having a first thickness and a first refractive index, and
• a (1-2)-th barrier layer disposed on the (1-1)-th barrier layer and having a second thickness greater than the first thickness and a second refractive index less than the first refractive index, wherein the first thickness and the second thickness are chosen such that reflected light from a bottom surface of the (1-1)-th barrier layer destructively interferes with reflected light from a bottom surface of the (1-2)-th barrier layer and wherein the bottom surface of the (1-2)-th barrier layer is closer to the (1-1)th barrier layer than a top surface of the (1-2)-th barrier layer and the bottom surface of the (1-1)-th barrier layer is farther from the (1-2)-th barrier layer than a top surface of the (1-1)-th barrier laver.
