Claim 13:
14. A display panel, comprising: a first substrate and a second substrate disposed oppositely, and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein
the first substrate comprises a first polarizer disposed on a side of the first substrate away from the second substrate, and 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, wherein % 180 is a symbol for a modulo operator, which means that a result from an expression inside a parentheses before the symbol is divided by 180 and a remainder is returned.
