Your close-up photo of the screen shows what is most likely dust or other debris situated between the outer layer (the digitiser panel) and the main LCD screen. The spots that you see (and have photographed) are not sharply defined - as would be seen if the issue was due to dead or stuck pixels.
As such, the good news is that the LCD display itself is unlikely to be defective - and that the observed problem is due to dust or dirt that has managed to find its way into the screen assembly.
As correctly mentioned by bobseufert, the entry-level iPad10 does not have a laminated screen assembly. Your iPad is not environmentally sealed; dirt, moisture or other contaminants can enter the iPad's casing through its available openings and potentially find its way between the digitiser-glass and the LCD screen. iPad models that do have a fully laminated screen are not susceptible to this specific problem.
Now the less good news... you have three core options to consider:
1) You might consider service of your iPad - but as the iPad10 does not have a laminated screen, the problem may reoccur at some time in the future
2) You might do nothing - and live with the problem.
3) Consider trade-in of your iPad against purchase of a more recent (and better) model of iPad.
For practical purposes, in lieu of servicing/repairing and returning your own iPad, Apple usually exchange a qualifying the iPad for a renewed/refurbished iPad of the same model and specification. The cost of the exchange is the same as would otherwise be charged for repair. If within your one-year warranty period, if accepted as a warranty problem, the exchange will cost you nothing. Otherwise, unless you have benefit of an active AppleCare plan, an out-of-warranty repair may be expensive - but somewhat less than the cost of purchasing a replacement iPad.
As for out-of-warranty costs, Apple offers a fixed-price price repair. You can verify eligibility and cost for your region/country here:

If you have an active AppleCare+ plan, the cost of repair is reduced to a small excess/deductible fee.
