Abstract

Disclosed are a flat display panel that is capable of preventing a different appearance between a camera index light source (CIL) and an ambient light sensor hole and a method of manufacturing the same. The flat display panel is configured such that, on a first substrate, partitioned into a pixel region of a display area and a CIL hole part and an ambient light sensor hole part of a non-display area, a gate insulating layer, a first passivation film, a planarization film, and a second passivation film are not present at the CIL hole part or at the ambient light sensor hole part or such that only the planarization film is present at the CIL hole part and the ambient light sensor hole part.
