Abstract

The invention provides a display device which includes: a first substrate including a pixel area and a transmissive area; a thin-film transistor on the first substrate; a planarization layer on the thin-film transistor; a first light emitting electrode on the planarization layer; a bank covering a part of the first light emitting electrode; a light emitting layer on the first light emitting electrode; and a second light emitting electrode on the light emitting layer and the bank. The transmissive area includes a transmissive hole penetrating the bank and the planarization layer.

Description

technical field [0001] Aspects of example embodiments of the present disclosure relate to a display device. Background technique [0002] As the information society develops, demands for display devices for displaying images are increasing in various forms. For example, display devices are being applied to various electronic devices such as smart phones, digital cameras, notebook computers, navigation devices, smart TVs, and the like. The display device may include a display panel including a plurality of pixels connected to scan lines, data lines, and power lines to display images. In addition, the display device may include, for example, an image sensor for capturing an image of the front surface of the display device, a proximity sensor for sensing whether the user is located near the front surface of the display device (eg, near or adjacent to the front surface of the display device), Various optical devices of an illuminance sensor for sensing illuminance of a front s...
