Claim 15:
16. A preparation method of the display panel according to claim 14, comprising:
forming a first substrate and a second substrate respectively,
cell-assembling the first substrate and the second substrate, and filling liquid crystal between the first substrate and the second substrate; and
attaching a first polarizer to a side of the first substrate away from the second substrate, wherein the first polarizer comprises a first quarter-wave plate, a second adhesive layer, a half-wave plate, a third adhesive layer, a first cellulose triacetate layer, a first poly vinyl alcohol layer, and a second cellulose triacetate layer which are sequentially arranged along a direction away from the second substrate, wherein an absorption axis angle of the first poly vinyl alcohol layer is n°, a slow axis angle of the half-wave plate is ((n+21)%180)° to ((n+23)%180)°, a slow axis angle of the first quarter-wave plate is ((n+142)%180)° to ((n+144)%180)°, and n is between 0 and 180.
