First, fourth and fifth chords in major scale will always be major chords. Second, third and sixth chords will always be minor chords. Seventh chord will always be diminished chord.

I. D – F♯ – A (D major chord)
ii. E – G – B (E minor chord)
iii. F♯ – A – C♯ (F Sharp minor chord)
IV. G – B – D (G major chord)
V. A – C♯ – E (A major chord)
vi. B – D – F♯ (B minor chord)
viiº. C♯ – E – G (C Sharp diminished chord)
These are the chords that harmonize the D major scale. They are the harmonic chords that are diatonic to the D major scale.
