Go to digikey.com, search for LCD. Under the "Optoelectronics" section, click on "Display Modules - LCD, OLED Character and Numeric". I'm assuming you want a character display and not a graphical display. From there, you can use the filters on the top to find something that fits your needs. I would guess the filter categories you're most interested in are "Display Format" (number of characters x number of lines), "Voltage - Supply", and "Interface".
Once you've filtered a bit, you can sort by price (if that's important to you) and pick out a display that you like.
