Abstract

Provided is a display device. The display device includes a display element layer, a light blocking pattern layer disposed on the display element layer, and an input sensing layer disposed on the light blocking pattern layer. The display element layer includes a plurality of pixel defining films and a protrusion disposed on at least one pixel defining film, the light blocking pattern layer includes a light blocking part that overlaps the protrusion and an opening, the input sensing layer includes a plurality of sensing electrodes and a plurality of intersections where the sensing electrodes cross each other. The protrusion, the opening, and at least some of the plurality of intersections overlap each other.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0147657 filed with the Korean Intellectual Property Office on November 18, 2019, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] Embodiments of the present disclosure herein relate to a display device, and more particularly, to a display device including a light blocking portion disposed on a lower portion of an input sensing layer.
