I just bought a new Lenovo IdeaPad Z500 and it has a 15.6 inch mate display, before this I had a laptop with glossy display, so I see something strange and I don't know if this makes the difference between a mate and a glossy type of display but mine, if i have a one color wallpaper or in places where a single color predominates on a larger surface, I can see some minuscule squares(like the matrix of the display or something) on the entire display, is this a problem with the display?
Thank you in advance!

Welcome to the Forums.
Your issue might be similar to this thread.
Can you try to download and install Passmark's BurnInTest standard edition and do a burn-in test on your CPU and GPU (2D and 3D tests) for 15mins and observe.
The image of the test should be smooth as the one below::
If you get granules on the image like the one below, there's most likely a GPU rendering issue and you may need to contact lenovo or the vendor to report the issue:
Hope this helps

Thank you for the reply.
I don't have any problems with the GPU in terms of rich graphical games, I play Battlefield 3, Dota 2 and many other new games with no GPU artifacts.
I thought that may be the display matrix wich is more visible than my previous laptop, could be that? It looks like that kind of squares that can be seen with a foto camera using macro for close-ups but I can see them on some colors with my eyes only.

One way to know if there's an issue with the display is to use an external display via the VGA/HDMI. If it works fine there with no artifacts then you may need to call lenovo or the place where you got it from and report the issue.

Please take a look at these pictures made with my cellphone. I resized to be able to upload them. You can see the grid of very small squares all over the image, I can see this grid on some colors with my bare eyes. Is this normal?

Depending on the thickness and layering of tje matte surface (pixels), grainy or hazy texture may appear in some instances (usually when displaying light colors). The pictures you uploaded seems normal for a matte finish screen.
