Claims (12)

  1. A polarizer and a light-transmitting film having birefringence in the plane (excluding a light-transmitting film having a retardation value of 3000 nm or more) provided on the viewer-side surface of the polarizer. A polarizing plate,
    The polarizer is arranged so that the absorption axis direction of the polarizer is along a horizontal direction, and the direction having the highest refractive index in the plane of the light transmissive film is defined as a slow axis direction, and the retardation in the plane is When the direction orthogonal to the phase axis direction is the fast axis direction, the light-transmitting film is disposed so that the angle of the fast axis direction with respect to the absorption axis direction is 5 degrees or more and 40 degrees or less. A polarizing plate that is characterized.
  2.   The polarizing plate according to claim 1, wherein the light transmissive film is a polyester film.
  3.   The light transmissive film has a refractive index in a direction parallel to the fast axis direction of the light transmissive film, which is formed on the surface opposite to the surface on which the polarizer is formed in the light transmissive film. The polarizing plate according to claim 1, further comprising a functional layer having a refractive index lower than the refractive index in the fast axis direction.
  4.   The polarizing plate according to claim 3, wherein the functional layer is a hard coat layer or an antiglare layer.
  5. The polarizing plate according to claim 1, wherein the retardation value of the light transmissive film is 80 nm or more and 150 nm or less.
  6. The polarizing plate of Claim 1 whose retardation value of the said transparent film is 138 nm or more and 2900 nm or less.
  7. Comprising a polarizing plate according to any one of claims 1 to 6, the absorption axis direction of the polarizer is disposed the polarizing plate along the horizontal direction, the image display device.
  8. The image display device according to claim 7 , wherein the image display device is a VA mode or IPS mode liquid crystal display device.
  9. Comprising a light-emitting diode as a light source, an image display apparatus according to claim 7 or 8.
  10. The polarizing plate according to any one of claims 1 to 6 , wherein the polarizing plate is disposed in an image display device so that an absorption axis direction of the polarizer in the polarizing plate is along a horizontal direction. To improve contrast in bright places.
  11. The improvement method according to claim 10, wherein the image display device is a VA mode or IPS mode liquid crystal display device.
  12. The improvement method of Claim 10 or 11 provided with a light emitting diode as a light source.
