Liquid crystal display monitors are made of

Options

A. Monocrystals
B. Single crystals
C. Liquid crystals
D. Polycrystals

Answer

To answer the question about what liquid crystal display (LCD) monitors are made of, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding the Components of an LCD**:
- An LCD monitor consists of two glass substrates. These are thin layers of glass that form the outer boundaries of the display.

2. **Liquid Crystals**:
- Between these two glass substrates, there is a layer filled with liquid crystals. Liquid crystals are substances that exhibit properties between those of conventional liquids and solid crystals. They can flow like a liquid but have some degree of ordering, which is crucial for their function in displays.

3. **Functionality of Liquid Crystals**:
- When a light source is directed towards the LCD, it first hits the first substrate. When electrical current is applied to the liquid crystals, they align in a specific way that allows certain amounts of light to pass through.

4. **Color Production**:
- As the light passes through the liquid crystal layer and then through the second substrate, it can produce different colors based on how the liquid crystals are aligned and how they interact with the light.

5. **Conclusion**:
- Therefore, the correct answer to the question is that liquid crystal display monitors are made of **liquid crystals**.
