You have three options:

  1. Use a CD4050BE chip to connect the CS, MOSI MISO and SCK lines, between the screen and your arduino.

  2. Use a 5V / 3V3 voltage divider on each of the CS, MOSI MISO and SCK lines between the screen and your arduino.

  3. Use a 3.3V arduino UNO and directly connect the screen

Never connect your screen directly to the 5V arduino UNO, as you risk damaging it
