picture of water possible water damage

In a maniac episode, i started cleaning the house rough with water and splashed water on the laptop. Everything seemed fine, i turned it off and let it dry for 2 days.

Today when i turned it on it has this strange area with lighter contrast.

The outside of the damaged area is so straight, i wonder if i cleaned my screen with a too rough sponge or cloth.

Today i was heating the laptop all day with cpu stress test and blocking the vents, the screen is hot but no change in the affected area.
