Abstract

The present invention relates to a method for improving the visibility of a display and an electronic device for implementing same, the electronic device comprising: a display panel including a polarization layer and a phase delay layer; an impact absorbing member disposed below the display panel and having an opening; an image sensor disposed corresponding to the opening; a first phase delay member disposed below the display panel to correspond to the opening such that a part of the light passed through the display panel and rotating in a circular direction of a first direction vibrates linearly in the first direction; a polarizing member disposed below the first phase delay member; and a second phase delay member disposed below the polarizing member such that a part of the light transmitted through the polarizing member and vibrating linearly in the first direction may rotate in a circular direction of a second direction.
