You'll want to be reviewing the data sheet/manual.

but any specific things could make me sure it will work on stm board ?

This seems to be an ST7735R based display, interfaced with SPI.

but any specific things could make me sure it will work on stm board ? As the stm32f4 MCU on the discovery board has several SPI interfaces, I see no specific problem. Just get some driver code (from Adafruit, for instance), and adapt the low level SPI driver. With a proper search engine, you might even be able to find examples for the stm32f4.

thnx!

so any lcd tft with spi interface could be connected to stm ? Basically yes, but you might need to check/compare the LCD interface spec. and the STM32 SPI spec. Don't expect extreme graphics performance, and better have a scope ready for debugging. Possibly this might help:
