The goal of this talk is to construct the p-adic Local Langlands correspondence for GL_2 for the 2-dimensional irreducible dihedral p-adic Galois representations. P. Colmez constructed such a correspondence for any p-adic Galois representation via the theory of (\phi,\Gamma)-modules. Our method is completely different from his and we use more representation theoretic technic not using any (\phi,\Gamma)-modules. We do this by constructing a $p$-adic theta correspondence between p-adic characters of a quadratic extension field E of Q_p and admissible p-adic Banach representations of GL_2(Q_p).
