  Advantages of CRT:

- Cheap (not the least because the technology has existed for over 50 years).
- Excellent contrast and brightness.
- 180-degree viewing angle from all directions.
- Practically no limit in color depth.
- Easy (on hardware) to achieve any resolution and aspect ratio (up to a
  point, of course).

  Disadvantages of CRT:

- Requires bulky and heavy displays due to the nature of the technology.
- Can suffer from several types of distortions (eg. the color channels
  not being perfectly aligned).
- Can suffer from some degree of blurriness.
- Usually poor refresh rates at higher resolutions.
- Energy consumption and heat production.

  Advantages of LCD:

- Very thin and light displays.
- No distortions.
- Sharp image, no blurriness.

  Disadvantages of LCD (most of which are getting better as the technology
advances):

- Expensive (being relatively new technology).
- Relatively poor contrast (but it's fastly getting there).
- Often suffers from narrow viewing angles, especially vertically.
- Often has limited color depth, requiring software dithering, which
  reduces image quality.
- Dead pixels, which may be more annoying than the CRT distortions.
- Fixed resolution. Any alternative resolution has to be simulated by
  scaling pixels, which may produce ugly results for resolutions and
  aspect ratios which are not exact multiples of the resolution of the
  display.
- Can suffer from ghosting (especially older LCDs).
