Squared shadow white screen under sunlight

[wirazo]

Hi,
Today I noticed when I was watching a white screen, under direct sunlight, a squared shadow, in the same position as in the picture below, have you guys noticed the same? I don't know whether it's a defect or something else. Obviously, I was hard for me to capture a clear image of the screen with another phone.
