The LCD is used for displaying the alphanumeric character on its screen. The LCD display is consists of 8-data lines and 3-control lines which are used for interfacing the LCD display with 8051 microcontroller.

Consider the schematic representation of LCD on eagle software is,

Consider the PCB board layout after completing the routing between the terminals of LCD and header is,

After completion of board layout it is run to generate PDF. The PDF generated is used for taking the printout of above layout on Over Head Projector sheet (known as OHP sheets) or a wax paper for designing a PCB board.
