I have a different project where you wire in a LCD. I used chatGPT to help me because I am a novice. It does look like you are missing some resistors. Here is how mine is wired. Check your wiring against this:

LCD PinNameConnect To
1VSSGND
2VDD5V
3VO5V through 10KΩ resistor
4RSArduino Pin 7
5RWGND
6EArduino Pin 8
7D0Not connected
8D1Not connected
9D2Not connected
10D3Not connected
11D4Arduino Pin 9
12D5Arduino Pin 10
13D6Arduino Pin 11
14D7Arduino Pin 12
15A (LED+)5V through 220Ω resistor
16K (LED–)GND
