I hope you didn't squeeze the display because if you did, you may have just damaged the LCD display panel.

Applying slight pressure on the screen is ok to see if marks appear which would indicate screen + backlight is turning on but no image is being produced.

Might want to try one of the display outputs from the side of the MacBook I think it's mini displayport so you will need to use an adapter if you want to plug HDMI in.

This is a tricky one! Did you get your system wet at some point or have some liquid spillage into the keyboard?

The Air’s use the graphics engine of the CPU and as we can see the displays image is present so we know the CPU & graphics engine of the chip is working. Yet the crosss hatch (H&V) implies a logic board signal issue.

Are you really pressing on the display its self or just pressing on the brightness button?

At this point I think you’ll need to plug in an external display to see if the image is clean on it. If it is thats points to the internal display needing replacing if not then that points to the logic board has issues.

No water spill ever happened.. it just happened when I was normally working on the laptop .. I will try to connect an external display and check.. is there any possibility of loose contact of the display wire?. Yesterday night I couldn't see anything now. The screen shown with lines

The clear display image under the cross hatch lines tells me the connection is good between the logic board and the display. Until you try the external we just don't know which is bad here.

You could try running the onboard diagnostics but I don't think an error will pop and depending on your OS version diagnostics may not even work as Apple has a bug in the newer firmware killing it. Restart your system and press and hold the D Key to enter. I'm sure the display will still be bad under it.
