It could be "light bleed": There are LEDs under the LCD screen that act as a backlight, shining through the screen. Bleed occurs where the internal layers of the screen separate in some way so that light from the LEDs is hitting the front/side of the screen, distorting the image, rather than coming up from under it as normal. If you google "LCD Light Bleed" you can see other examples.

Similarly, it could just be some other form of damage or manufacturing defect of the display.

Your phone is new enough that you can likely get it repaired under warranty as a manufacturing defect, so that would be my recommendation.
