LCD, or Liquid Crystal Display is a type of thin, flat display screen frequently used in digital cameras, to display images, menus and settings, and also to display settings in some film cameras. On most digital cameras that have them, LCD displays are (or can be) used as the viewfinder, and many do not have any alternative way of composing shots. However, it seems that the majority digital SLRs can only view results on their LCD panels, and frames must be composed using the TTL reflex viewfinder.

LCDs may be made as pixel-oriented arrays, capable of showing full photo images as described above, or fixed-format, able to display only pre-defined symbols. Simple versions of the second type can be found on early low-resolution consumer digicams, or as frame counter and function control display on versatile automatic analog cameras.
