Your laptop is a valuable asset, so keeping it in good condition is a priority. Even though it's on the inside of your laptop, your screen will still get dirty from everyday use. The screen being made of such fragile material, you want to avoid any damage to the screen with harsh cleansers. You can clean the inside of the screen by taking it apart.
Taking the Screen Apart
Pop out the rubber stoppers which are covering the screws that hold the screen frame in place, and unscrew each screw. Pull off the frame.

Grab the screen by the edges and gently lift it out from the laptop. A cable connects the screen to the laptop using screws on some models, or a clip function on others. Remove the cable form the screen and set the screen face down on a protective surface.
Peel back the protective circuit board cover (usually a thin film) from the back of the screen from the top first. You will expose the first set of screws on the side of the screen's edge, which hold the circuit board protector to the circuit board. Remove the screws, and then lift up the film to expose the next set on the bottom edges; remove these screws as well.
Remove the screen frame from the LCD. Carefully lift the circuit board, which is attached to the LCD. You will expose the metal frame holding the screen frame in place with several tabs. Lift the tabs on the top edge of the screen. The screen comes apart in three sections: the screen frame, LCD, and background. Remove the screen frame to gain access to the other side of the screen.
Cleaning the Screen
Examine your screen to determine whether there is only minor dust and dirt or there is heavier dirt such as fingerprints or grime.
Mix a cleansing solution appropriate for the amount of dirt on your screen. For minor dirt, use just distilled water. For more grime and oils on your screen, mix a solution of equal parts of distilled water and either isopropyl alcohol or white vinegar to create a solution in the spray bottle. Pour the solution into a spray bottle.
Spray your cleaning solution or distilled water onto the cloth, being careful not to over saturate the cloth.
Wipe the screen gently with the cloth. Use horizontal or vertical swipes across the screen, taking care not to press too hard. Focus on the oil spots in soft circular rubs.
