No, it will not work. LCD blocks all UV and a lot of usable light. LCD projectors do not work to cure resin.

We have been using the 3-LCD Epson projectors for years. You just need resins that are sensitive up into the Blue spectrum ~460nm.
Use resins that cure from UV up past Blue like these:

The "consumer" resins only cure from UV up to just past 410nm. As Phife mentioned they won't work with Blue (460nm) light since it's way above the range of sensitivity of those resins.
