The major 7th chord (abbreviated maj7 in chord names) is a four-note chord, but due to the characteristics of the guitar the chords can involve four to six notes (in some cases with duplicated notes). The major 7th is not to be confused with the dominant 7th.
The chord is built by a root, a major third, a fifth and a major seventh. There are many ways to play these chords. Below you can see maj7 chords in open positions presented in pictures and by scrolling down further you could also see maj7 barre chords.

A triangle in the chord name
"Major" can instead be represented by a small triangle (a delta symbol). In these cases, the chord name and the "7" has a tringle amid them (which often is in superscript).
C△7 [C triangle 7] = Cmaj7

Theory
To look closer at this certain chord type we can take Cmaj7 as an example. Cmaj7 consists of four notes: C, E, G and B. Played as an open chord on the guitar it includes the following notes (from 5th to 1st string): C, B, G, B and E. The B note is duplicated, but not because it's the most important note, but because of the circumstance of the instrument and how it's tuned.
Movable barre shapes for major 7th chords
Emaj7 shape
Amaj7 shape
Comments
These two shapes can be used for all maj7 chords and the root note is the bass notes on the 6th and 5th strings respectively. The reason for the names "Emaj7 shape" and "Amaj7 shape" is that the shapes are based on Emaj7 and Amaj7 shapes in open position (see above). So, if you place the barre finger on the first fret and uses the Emaj7-shape, that makes you play Fmaj7.
A movable shape with bass note on the fourth string is, with Cmaj7 as an example, XX5557, (notice that this version is an inversion).
