Screen shows negative from different angles. (From below)

Today I have bought my new budget laptop Lenovo ideapad 120S-11IAP.

 

Direct link of the product: https://www.emag.bg/laptop-lenovo-ideapad-120s-11iap-s-procesor-intelr-celeronr-n3350-up-to-2-40-ghz...

 

Soo, when you look your display from a different angle, like below or up, the colors of the display change to a negative.

Example of the issue (NOT MY LAPTOP ON THE PICTURE): https://i.imgur.com/rjQGXVU.jpg

My issue, fully described: http://blogs.plos.org/mitsciwrite/2013/05/02/your-computer-screen-from-an-angle/

 

Soo, is it just this the screen of the model of the laptop, which I bought or it shouldn't be like that. I just want to know if it's a issue only for my piece or to all pieces of this series.

 

Should I return my laptop?

There are several different technologies that are used for LCD screens.

 

The cheapest screens are those that use TN technology.  These usually have fast response (so good for games), but these screens are highly directional.  If you view these at an angle, you can indeed get the "negative" effect.  My 500-15ISK is like this.

 

More expensive screens use IPS technology.  These are slower than TN (so perhaps not quite so good for games, although you may not notice), but these screens have a much wider field of view.  You can view from an angle without the brightness varying.  So no "negative" effect.  My 700-15ISK is like this.

 

The most expensive screens use OLED technology.  These are used in expensive smartphones and expensive TVs, but I am not sure whether there are any laptops/tablets that use OLED.

 

I am not familiar with your particular laptop, but from your description it sounds as though it has  a TN screen, and so the "negative" effect is to be expected when viewing at an angle (i.e. it is not a defect in your particular sample).

In the specifics, it says that the display is:

 

- 11.6 inch

- HD

- LCD LED

- Antireflex screen - from lights outdoor etc

- 1366x768 resolution

 

Soo is it a such display? TM or what is called? Should this display have this issue?

None of the details specified indicate the technology used for the screen.

 

If you are unhappy with your sample, go back to the seller and see if they will exchange your sample for a different one, or allow you to exchange it for a more-expensive model that has an IPS display (you would need to pay the difference in price, of course).
